I am currently trying to set-up a Sitecore project on my PC. When I go to view the project on my browser I get the following error:
Sitecore Cannot open database "marktwoSitecore_Web" requested by the login. The login failed. Login failed for user 'blah''.
These are the steps that I have carried out so far:
1) Firstly there are three types of sitecore installations to do:
- Complete
- Database only
- Client only
I have gone with the Client only installation.
2) The Sitecore "Client-only" installation instance was made inside the inetpub/ wwwroot folder.
3) I then made a visual studio project
4) I made a folder called "Libraries", which is located in the root of my visual studio project solution. I copied over all the relevant Sitecore.dll's from the wwwroot project to my visual-studio project into the Libraries folder. I also replaced the Default web.config file in my Visual studio project with Sitecore's version of Web.config. And then I added Sitecore references to my Visual Studio project.
6) With all of the initial configuration done; I set-up a publish profile so that I could publish my C# code to inetpub/wwwroot project. I did step four so that my publish would not overwrite sitecore dlls.
5) I changed the Connection strings in App_Config/ConnectionStrings.config to point to the Web, core and master sitecore databases. That were created during the Sitecore installation.
Those were the steps I did prior to getting the error about invalid login credentials. I am not sure why I am getting this error; since I went into Microsoft SQL server Management Studio and I gave the user "blah" admin rights to all of the datbases: Master, web and core.
Any support and guidance would be greatly appreciated; as I am unsure of how to address this problem
This error is happening because the web database referenced in your Website/App_Config/ConnectionStrings.config is either not there or the permissions are not set properly on that database. The easiest way to troubleshoot is to load SQL Server Management Studio specifying the host, username and password that are in your connection strings and see if it connects. It sounds like you are probably logging in with your Windows user when you are making the changes listed above.
You could try making the blah user a "db_owner" to see if that helps or your local instance may not be in "mixed authentication mode" which allows for named users and windows users. You can change that in the settings, but you need to restart the service for it to take effect.
I am running Visual Studio 2010 on a Windows 7 VM and trying to build a fairly large solution. When I try to do so, I get the error:
Cannot register assembly "C:\Development\ProjectName\Source\bin\Debug\AssemblyName.dll" - access denied. Please make sure you're running the application as administrator. Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))
I have taken the following steps:
Confirmed that I am in fact running Visual Studio 2010 as administrator.
Restarted the VM.
Confirmed that the assembly does exist exactly where Visual Studio is looking for it.
Confirmed that administrator has full control over the relevant file.
Cleaned and rebuilt the project (multiple times).
I have also found that building the project which creates AssemblyName.dll, manually registering it with RegAsm, and then building the project which requires AssemblyName.dll does not result in an error, but this is not a desirable workaround as it requires manual control. Can anyone give me some advice on how to solve this problem?
Many thanks.
This particular issue happens when you are building an assembly project which has the 'Register for COM interop' checked under the Compile tab of the project properties. As Stephane said, you must right click -> Run as Administrator in order for it to register automatically.
If you already have the compiled assembly from a different machine, you can alternatively register it manually and reference the compiled assembly with the project to by-pass the issue.
When you ran VS2010, did you right-click and select "Run as administrator"? If not, it actually runs as a lower priviledged user. Once I selected "Run as administrator", this problem went away.
I also ran into this error even though I was running VS 2015 as administrator.
In my case I found that manually cleaning up (ie deleting) bin\Debug\*.* for the project resolved the issue. Apparently some kind of file permissions or something was preventing the operation, and the error message may have been incorrect.
I'm not sure what was causing the file 'conflict' in the first place.
Similar to what UuDdLrLrSs said, when I tried to clear the bin folder, Windows gave an error on file access. Apparently another process was using the file - in my case, Microsoft Access.
After closing the associated program that had a file handle, the project built fine. (Although I'm still a little confused as to why it had a file handle on debug assemblies...)
Recently I have been working on a project and have been waiting to publish it to Azure. Before I was able to do this my local user account on my machine was changed. Now when I try to add the project solution to the solution control explorer I get "access to path [old username]/my documents/projects is denied." I have the project copied from the old user account onto the new one I am using. I opened from this location, but it still seems to reference the old path. How do I change this and/or what settings do I need to change?
I have uploaded the project into the source control explorer for the project, and the rest of the team can view it. It is possible to re-load the project from here and create a new work space mapping on the new local account? If so how can I do this?
I managed to get it moved by doing the following, thanks jessehouwing for the push in the right direction.
Closed Visual Studio
Went to old account, copied project directly to the C drive
Went to the new account, opened the project from there
Deleted mapping referenced in the picture in jessehouwing's answer
Created new mapping under a different name, because even though the old one was removed, there was still a naming conflict (I have no clue)
Mapped the source control and local folder from scratch
You will have to change your workspace mapping. If the Source Control Explorer allows you, you can open the Workspace dropdown (in the toolbar) and edit the current mapping.
If the Source Control Explorer doesn't allow you due to Access Denied errors, you can also use the commandline utility tf.exe to remove them.
tf workspaces /remove
And then create a new one through the UI or also from the commandline using
tf workspace /new
tf workfold /map
I'm re-using an old picture here, step 4 should be to fix the paths in the Workspace folders list on the bottom of the dialog :).
This is still happening in 2022 and below are steps we have resolved this "Access Denied" in visual studio (2019 in our case) for Azure DevOps Server.
Open visual studio command line and run the command;
tf workspace /delete “WORKSPACE_NAME;OWNER”
Open folder C:\ProgramData\Microsoft Team Foundation Local Workspaces and delete anything folder inside
Verify C:\ProgramData\Microsoft Team Foundation Local Workspaces
folder has the user you are logged into the machine as full access
Go back into Visual Studio and reestablish your workspaces and
perform a get latest
I have a problem debugging a project migrated from Visual Studio 2010 to 2012. Every time I go to debug it I get the error message:
"Error HRESULT E_FAIL has been returned from a call to a COM component".
Compiling and running the application in a local IIS server works fine - just cannot debug.
The other change other than moving to VS2012 is I am now using Team Foundation Server for source control and issue tracking - but I cannot see how that would affect it.
I can narrow it down to the following
The project file - it has been migrated from VS 2003 as a website project and has been chopped and changed up the different versions
Crystal Report runtime library/ some other library
Anyone with any ideas?
I had the same problem with a c++ project in Visual Studio 2019.
The following solution worked for me:
Close Visual Studio.
Go to the project's root folder and delete the .vs directory.
Start Visual Studio and open the solution.
The build should now work.
I have been getting this a lot lately. I've been having to create a new file and move the code to the new file to get around it.
I fixed it by deleting the solution's suo file (as far as I can tell, it just stores info like what files are open in the IDE and stuff, and deleting it does no real damage).
My file was seemingly corrupt. (The IDE wouldn't remember what files were open when restarting. It was 1.7MB in size, which seems large, even for my 40 project solution, which rarely has more than 50 files open at once.)
Edit: I just recently had to do this in VS2017 but for another reason, it was taking longer to build and took 5+ minutes to stop a debug session, deleting that pesky suo file fixed it right up, now anytime VS acts weird deleting SUO is my first port of call.
I removed the csproj.user files and it worked for me.
In some other cases, to fix this error, I go to Web tab in the project properties and check "Use Visual Studio Development Server" and "Auto-assign Port". After that I need to rebuild the project and restart VS
This solved my problem:
Start —> Run —> regsvr32 %SystemRoot%\System32\msxml3.dll
Start —> Run —> regsvr32 %SystemRoot%\SysWOW64\msxml3.dll
Before this I tried the above solution from Simon, but didn't work for me!
Perhaps combining these two solutions did the job!
Sorry to revive a dead thread but i solved this on VS2017 by deleting the project template cache and item template cache folders in
%localappdata%\Microsoft\VisualStudio\[BUILD]
Then resetting the visual studio settings via
Tools>Import and export settings>reset all settings
Also ive heard turning off "Lightweight solution load for all projects" can help.
Doh! In case anyone else gets this error when trying to attach to an IIS Website.
Triple check that your hostname is correct, I had forgotten a '/' in (e.g.) http://my.testsite.com
Try this before re-installing Visual Studio like I did.. Terrible error message..
I wanted to add that I encountered this error when opening designer file in WinForms app. My issue was that one of the references in the project was referencing itself. Apparently this can happen as mentioned here
https://social.msdn.microsoft.com/Forums/office/en-US/00aede04-d8cd-4475-8114-4b4792261052/winforms-designer-error-hresult-efail-has-been-returned-from-a-call-to-a-com-component
I removed the reference and it is working fine.
Maybe this page helps:
Scenario Two:
The Microsoft Visual Studio 2010 IDE crashes while creating OR debugging a web application project.
This above error occurs because of corrupted Cache of Visual Studio 2010. In order to resolve the issue just delete the project Cache from the below location:
C:\Program Files\Microsoft Visual Studio 10.0\Common7\IDE\ProjectTemplatesCache
C:\Program Files(x86)\Microsoft Visual Studio 10.0\Common7\IDE\ProjectTemplatesCache
Then run devenv.exe /setup to re-build the cache.
I tried all of the above solutions none work for me, I found the solution here
Open ActivityLog.xml by going into
C:\Users\{UserName}\AppData\Roaming\Microsoft\VisualStudio\15.{Id}
Check if error states that
"CreateInstance failed for package
[ReferenceManagerPackage]Source: 'mscorlib' Description: Could not load type
'Microsoft.VisualStudio.Shell.Interop.' from assembly
'Microsoft.VisualStudio.Shell.Interop.11.0'
Then run this gacutil command through VS Cmd prompt (admin mode):
Navigate to
C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\Common7\IDE\PublicAssemblies
Run gacutil -i Microsoft.VisualStudio.Shell.Interop.11.0.dll
It seems that to bring up the Add Reference dialog in Visual Studio 2017 the Microsoft.VisualStudio.Shell.Interop.11.0.dll needs to be regsitered in the GAC. You can follow these steps to register this assembly in the GAC:
Open the Develop Command Prompt for VS2017 (ensure you run the as administrator otherwise the GAC registration may fail)
Change the current directory to the PublicAssemblies folder for your Visual Studio 2017 installation. Mine was:
C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\Common7\IDE\PublicAssemblies
Run the following command to register the assembly in the GAC:
gacutil -i Microsoft.VisualStudio.Shell.Interop.11.0.dll
C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\Common7\IDE\PublicAssemblies>gacutil -i Microsoft.VisualStudio.Shell.Interop.11.0.dll
Microsoft (R) .NET Global Assembly Cache Utility. Version 4.0.30319.0
Copyright (c) Microsoft Corporation. All rights reserved.
Assembly successfully added to the cache
Now restart VS2017 and try to add a reference to your project again and you should see the Add Reference dialog appear.

https://camerondwyer.com/2017/05/03/how-to-fix-the-operation-could-not-be-completed-error-adding-reference-to-visual-studio-2017/#more-2286
I found the solution below on https://developercommunity.visualstudio.com/content/problem/260196/add-a-reference-raise-error-error-hresult-e-fail-h.html address.
It worked for me in VS 2019:
1 Open "Developer Command Prompt for VS 2017" as Admin
2 CD into "C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\Common7\IDE\PublicAssemblies"
3 Run "gacutil -i Microsoft.VisualStudio.Shell.Interop.11.0.dll"
After a restart, it all worked well.
I had the same issue after an upgrade from VS2013 to VS2015.
The project I was working at referenced itself. While VS2013 didn't care, VS2015 didn't like that and I got that error. After deleting the reference, the error was gone. It took me around 4 hours to find that out...
Just delete packages folder.That helped me
Root Cause:
Microsoft.VisualStudio.Shell.Interop.11.0.dll is missing from GAC.
Solution:
1. Go to start menu and Open Command Prompt for Visual Studio
2. Enter command gacutil -i Microsoft.VisualStudio.Shell.Interop.11.0.dll
3. If in case your system unable to find this dll file then you may download it from Nuget package manager and then can provide the path of dll
All set! hit enter and you're done!
In my case, it seems it was because I stashed some files, but some related windows remained open.
Closing all windows and rebuilding solution fixed it for me.
I wrote a simple program to open different folder while clicking on some specific buttons. I made the file properties as "content" and "copy if newer" to make deployment. So if I installed the exe file in the other software it actually install all of its resources and run the program fine.
So, this is all about my program. While developing this sometimes if I run the program to check, it showed the error
"HRESULT E_FAIL has been returned from a call to a COM component"
and I could not open the designer view. But Somehow I got an easy solution for me. I am not sure whether it will work for other or not.
Here is the solution:
Copy the whole application folder to another location. click on the application file from there.
it will not work since it is just a copy and you will not see the designer
From the solution explorer delete the form1.vb ( or may be a different name if it was changed during developing)
In the solution explorer>right click>add an existing item> browse the file Form1.vb from where the folder is copied ( orginal location)
run the program in the new location. It will work
The problem with this solution if you want to add something and after running the program you find the same error, you have to copy the whole application folder in another location again and follow the above steps
Not sure about the exact reproduction steps for the error (HRESULT E_FAIL has been returned from a call to a COM component), but the solution for me was:
Close Visual Studio and Repair it through Control Panel.
Restart system
After the restart, the error was gone.
The error occurred for me after I installed the latest Windows 10 SDK. I was getting the error while building a C++ project using SDK 8.1. In Project properties, I switch to latest 10 SDK. rebuild. That worked. Changed back to 8.1. Rebuild. No error.
Steps to resolve the issue:
1.Open your solution/Web Application in VS 2012 in administrator mode.
2.Go to IIS and Note down the settings for your application (e.g.Virtual directory name, Physical Path, Authentication setting and App pool used).
3.Remove (right click and select Remove) your application from Default Web Site. Refresh IIS.
4.Go back to VS 2012 and open settings (right click and select properties) for your web application.
5.Select Web.In Servers section make sure you have selected "Use Local IIS Web Server".
6.In Project Url textbox enter your application path (http://localhost/Application Path). Click on Create Virtual Directory.
7.Go to IIS and apply settings noted in step 2. Refresh IIS.
8.Go to VS 2012 and set this project as startup Project with appropriate page as startup page.
9.Click run button to start project in debug mode.
This resolved issue for me for web application which was migrated from VS 2010 to 2012.Hope this helps anyone looking for specific issue.
My machine configuration is:
IIS 7.5.7600.16385
VS 2012 Professional
Windows 7 Enterprise (Version 6.1 - Build 7601:Service Pack 1)
This happens in our TFS build server some times (Gated check in). It is about workspace folder. I don't know why but workspace folder access sometimes corrupt. What I am doing to fix issue is deleting TFS build workspaces and deleting relevant workspace folders. TFS build machine then create new workspaces for itself and problem is fixed.
Tousif Ahmed's solution should work for local builds. Copy application folder to another place should do the same thing what I am doing in TFS build machine.
In my case, it appears that this message can be issued by Intellisense in Visual Studio 2013. The screenshot below shows the error at the bottom of VisualStudio 2013 after the first load of a customer project.
I started googling what causes this error, and decided to try deleteing the user.vxproj files as mentioned above. I found however that the project built with no issues, then after exiting and re-loading the project, I no longer received the error. So I'm assuming in my case, it was some corruption due to moving the project from the customers directory tree structure to my local development disk tree structure. The key here is that in my case, the problem was transient. I did NOTHING and the problem appeared to resolve itself. (Not generally a desirable thing as I didn't fix anything so it might come back).
I recently spent about 3 hours trying to fix this issue on my ASP.NET app running on local IIS. I had 'Override application root URL' specified and I specified the url with an ending forward slash (/) such as http://my.dev.com/. If I saved the project options and came back in it would show the overrided root url as http://http://my.dev.com. Once I removed the last forward slash it started to behave ok and the error went away.
HRESULT E_FAIL has been returned from a call to a COM component
In my case, it was because i had differents projects with same GUID in my solution. (Project was created by copy/paste)
My problem manifested with opening Win10 appxmanifest file (no pun intended). Simply installing Windows 10 tools and SDK (go to New->Project->Select Windows->Install Tools) fixed it.
Add on development initiated on x86 architecture or 64 bit system then it will run on 32bit system also.
but if you Add on development initiated on 32 bit system and then you want to do changes on source code in 64 bit
Note: if you are connected SAP Licence on server system then set the port and set server name through service manager otherwise System will give error:

I fixed the same issue by deleting ComponentModelCache folder
Close Visual Studio (if you haven’t done so already out of despair)
Open a file explorer window and navigate toyour AppData folder. You can get there by:
In the search bar, type %APPDATA%/.. and press enter
Alternatively, navigate to C:\Users\\AppData
Go into Local\Microsoft\VisualStudio\<version> where is 12.0 for Visual Studio 2013.
Delete the ComponentModelCache folder.
From here: http://withmartin.net/how-visual-studios-component-model-cache-can-be-a-pain/
I faced the same issue in Visual Studio 2017,
Do follow these steps:
Start —> Run —> regsvr32 %SystemRoot%\System32\msxml3.dll
Start —> Run —> regsvr32 %SystemRoot%\SysWOW64\msxml3.dll
Clean the Project.
Restart visual studio.
Step 1 and 2 were copied from Besnik Kastrati post.
I find this answer
click Ctrl+Alt+J
click (...) in the top
now you can add dll from Browse , .Net or another
After clicking the OK button click at (add to references in selected Project in solution explorer) (this is a green plus "+" button)
I got this error when trying to install a nuget package that I had previously downloaded and installed in another project.
Clicking Clear all NuGet Cache(s) under Tools > Options > NuGet Package Manager solved this for me
I encountered this error after installing VS2019 but while trying to open a large solution (20+ projects), with both vcxproj and csproj projects, that target VS2015. The csproj all loaded fine, while the vcxproj all failed with the OP's error. Deleting the .vs folder did not work.
What did work was setting VC++'s "Fallback Location", under the "Browsing Database Fallback" settings.

I set mine to D:\VC++\v16. Where I use v140 for VS2015 and v141 for VS2017. Also set "Always Use" and "Do not warn".
I have the following problem:
When I create a new project in Visual Studio, name it and hit enter I get the following dialog box:
Access to the path "C:\Users\Tamas\AppData\Temp\lyy03tab.2ey\Temp\Properties\AssemblyInfo.cs" is denied.
I haved changed the default location of the visual studio project, runed VS as administrator but still no result. When I navigate to the AssemblyInfo.cs file it is showed greyed out (like when you cut it). The permision set that are granted for the System,Administrators and my user are all but special permisions.
Can someone help ???
Thanks,
Tamash
Check if you can manually create a folder in Temp. You may want to have a look at the below links. Helpful links:
Unable to create C# Console or C# WinForm app projects in VS2008
The project file could not be loaded. Access to the path "path" is denied
MSDN: /ResetSkipPkgs (devenv.exe)
Else Try deleting the content in Temp directory. Try disabling antivirus if installed.
I have seen this in the past where a virus may have marked a folder or file as "Hidden". Check to be sure that all folders are not hidden and that all files are not hidden. You can do this by right clicking and going into that folder's or file's Properties.
