I have just upgraded from Visual Web Developer Express 2008 to Visual Web Developer Express 2010. However, I can't use it. When I try to create a new project I get a small dialog box that says:
Error writing the project file. Class not registered.
(source: yart.com.au)
I have tried reinstalling and repairing the product to no avail.
The problem was MSXML6 was corrupt.
The answer is here:
http://www.ferolen.com/blog/error-install-ms-sql-server-express-in-windows-xp-sp3-msxml6-sp2/
But then I couldn't uninstall MSXML6 which led me to here:
http://www.thewindowsclub.com/microsoft-retires-windows-installer-cleanup-utility and this download page
Then I reinstalled MSXML6 from http://www.microsoft.com/downloads/details.aspx?familyid=d21c292c-368b-4ce1-9dab-3e9827b70604&displaylang=en#filelist
and it worked.
Please go through the below site to know about ""Error writing the project file. class not register'"
http://technicalinformations.blogspot.in/2012/12/error-writing-project-file-class-not.html
FYI, after installing MSXML6 and still error happens.
type this in Run Box.
regsvr32 msxml6.dll

This error started showing from yesterday, I remember installing Web development packages and updates windows. Before that if was working fine.
If I reload project same error shows up.
The application which this project type is based on was not found.

I tried uninstalling Xamarin packages and reinstalling.
It did not solve the issue.
Now I am doing complete uninstall of MS Visual Studio 2017
Please note that no changes have been made to csproj or solution file.
I get the "xamarin project type incompatible" frequently. (VS2015)
The solution for me:
Close down VS.
In the src project folder delete the .vs folder.
Restart VS.
Complete uninstall of Visual Studio along with C++ distributables from Control Panel > Programs and Features and then re-installing Visual Studio fixed the issue. Seems its caused by errors in installation
Microsoft should code properly and let programmers know if there were errors and 'repair' option is supposed to fix them. I don't know why these things are missed out in roll-outs.
I am getting an "Unknown Error" (shown below) alert when I try to launch Visual Studio 2017 Community after successful installation.
UPDATE: After Force uninstall & reinstallation
remove this folder (or similar):
%LocalAppData%\Microsoft\VisualStudio\15.0_db2a872f
folder name 15.0_db2a872f could be different in your machine eg. 15.0_XXXXXXX
found in the vs startup log that processing of Progression_NativePackage_Component_x86.pkgdef bailed out, indicating an inconsistent extension installation
I only had to rename(if you wan't to back it up)/delete the following file:
privateregistry.bin
or
privateregistry.user.bin
depending on Visual Studio version.
%LocalAppData%\Microsoft\VisualStudio\15.0_********\privateregistry.bin
%LocalAppData%\Microsoft\VisualStudio\15.0_********\privateregistry.user.bin
After restarting Visual Studio 2017 you may need to activate Tools or Extensions again.
Please check if the machine has Symantec Workspace Virtualization Agent installed. Removing the product from add\remove programs fixed the unknown error while launching VS 2017.
Here is the detail of the product.
Product code: {785F9A4D-D113-43B3-AA1D-77AD777F0A2F}
Package code: {32DB9767-3EF7-465A-ADF2-7ECFD25ABC12}
Install date: 2015.05.21
Version: 6.4.1266
Publisher: Symantec
I ran it as Admin and it somehow booted up just fine after that. I was getting the same error even after making sure that all packages and SDKs were installed until I ran it as admin.
Basically, just go to the shortcut in Start or to the .exe in the files, then right click it and run as Admin or change it in the properties. Tbh, it seems like a temporary fix and I'd actually like to know the real source of the problem, but for now, I don't have to reinstall and repair over and over.
Same version: Visual Studio Community 2017 installed using the launcher
I have a same problem after update VS 2017 Enterprise to the build 26228.9.
Repair installation doesn't fix anything. Still I got "Unknown error" message immediately after start VS2017.
Fixing is possible by removing this folder:
"C:\Users\USER_NAME\AppData\Local\Microsoft\VisualStudio\15.0_xxxxxxx"
where xxxxxxxx is some hexadecimal number.
BUT AFTER THAT YOU LOSE ALL SETTINGS that you done on your installation of VS 2017 (except product license key appliance).
Sorry that I must say this, but:
Maybe will be better stuck on the VS2015 for now. Because MS still not has really fully functional build of VS for now.
VS 2017 is still ready for first experimenting only and not for real work.
It is same story like a was when VS2015 has been published. (after several days stop working).
I fixed it the same way as niclar by deleting folder 15_.*. It does however appear that renaming privateregistry.bin has same effect with less trouble.
As mentioned by Torbjorn, ReSharper and other Extensions can mess up, however no reinstall required.
Merely go to Tools > Extensions and Updates... > Scroll through list of Installed Extensions > Enable those that should be enabled.
I have a side by side installation with VS2015. After opening and closing VS2015 once, VS2017 ist starting again normally. Strange but helped in my case.
I only needed to delete or rename ApplicationPrivateSettings.lock within C:\users{your username}\AppData\Local\Microsoft\VisualStudio\15.0_c31ecfb9 folder.
I was experiencing this issue with Visual Studio Professional
when not running as administrator. (It worked Ok as administrator)
I used Niclar's solution of deleting the folders.
I found same issue after installing the extension and removing the folder "C:\Users\USER_NAME\AppData\Local\Microsoft\VisualStudio\15.0_xxxxxxx" solved my problem.
you can rename the Solution Name and reopen the Project it solved for me after repairing the VS Installation
I used to use vs 2012 for some month without any problem, today when I want to open my c# project , I got this error message:
This program has known compatibility issues
Visual Studio 2012 Express for Windows Desktop is incompatible with this version of Windows.
when I click Run program I got this error:
'Microsoft.VisualStudio.Editor.Implementation.EditorPackage' package did not load correctly
When I continue with this error message, another error message shows: Visual Studio has stopped working. I need to get it work as soon as posible, any idea?
I had a similar problem, installing this patch solved it: KB2781514
I just got this error in VS2013 after installing a VS extension. I fixed it by closing all instances of Visual Studio, then removing %LOCALAPPDATA%\Microsoft\VisualStudio\12.0\ComponentModelCache
Happened to me today on VS 2012. The Update mentioned by Jarek didn't install (it complained I already have more stuff installed). Deleting the folder mentioned by squeaky didn't work.
Finally fixed after I installed VS 2012 Update 4 : http://www.microsoft.com/en-us/download/details.aspx?id=39305
I'm trying to launch a project created by someone else in my local environment. I'm currently using the following products:
Visual Studio 2010 Ultimate version 10.0.40219.1 SP1 Rel
MVC 2
Windows 7 Ultimate
But when I double click on the .sln file I get the following error:
C:\Users...\Desktop\ContactManager\ContactManager\ContactManager.csproj : error : The project file 'C:\Users...\Desktop\ContactManager\ContactManager\ContactManager.csproj' cannot be opened.
The project type is not supported by this installation.
Please help me load my project. :)
Thank you,
Aaron
Turns out that I just needed to install MVC version 3. I guess the project that I was trying to open is using MVC3 and my machine only had 2 as you can see in my environment list above. I'm glad I was able to fix this BUT give me a better error message for crying out loud. Sheesh. ;)

I've come across this before. In my case, I had installed Microsoft SQL Server and, more importantly, BIDS. Whenever I would open a project that was created in VS2008, the VS version selector would identify this as a 2008 project and BIDS would try to open it (and this error would occur). What I did as a work-around is I would right-click on the .sln file and use the "Open With" to select VS2010. If that also works for you, you can change your defaults for what opens .sln files.
Another way to test this is to open VS2010 and then use the "Open Solution" menu option to open your solution. If this method works, you know the issue is the default program that is opening your .sln files.
In my case project needs to have MVC3 so at first i checked i have MVC3 template in Visual Studio 2010 (service pack 1 installed). I downloaded MVC3 installer frowm following link:

After installing my issue get resolved.
I'm trying to open a silverlight project in Visual Studio 2008 and getting this error.
The project type is not supported by this installation.
Let me tell you I did installed:
VS2008
SP1
Silverlight Tools 3
Silverlight SDK
Silverlight
And they were installed in the sequence they are mentioned here. Still I'm getting the same error.
Adding some more details which might be helpful in identifying the cause:
When I try to create a new silverlight project it gives me error "Object reference not set to an instance of an object". And shows "...project creation failed."
I tried unistalling all of the things and installing them again. It really took a lot of time but didn't solved my problem.
Any help appreciated.
Open the project.csproj file with another editor, delete whatever you find between
<ProjectTypeGuids></ProjectTypeGuids>
I've had the same error when I tried to open a solution which required VB.NET, despite everything (to my knowledge) being C#.
If you've done a full install of VS then try this solution: http://andrewgunn.blogspot.com/2008/03/silverlight-project-type-is-not.html
Let us know how it goes.
Do you know who the silverlight project was created by? If so, then contact them and ask them if they used VS 2008 or if they used VS 2010 beta 1/2 (VS 2010 has a lot more and better support for silverlight so it's probable)
If they used VS 2010, then just go to the microsoft website and download you a copy... it's free(right now)
(and if you'll be doing much silverlight development, I'd recommend downloading it anyway. It has code completion for XAML!)
run devenv /setup
