Trying to run an old project in Visual Studio 2015. It was created in 2012 or 2013, I cannot remember which. I have uninstalled both programs as I was running out of space, and i think that is what caused this. I get the following options:
And I do not want to change the target, so clicking on the second option brings me to https://www.microsoft.com/net/targeting which I can't seem to find anything there that remedies the situation. Is there a way around this without reinstalling the old version of Visual Studio again? Will that even fix my problem? Thank you.
Just Reinstall Visual Studio. When you uninstalled previous version it caused this problem.
You could try doing a repair reinstall of Visual Studio 2015.
Another point to consider is that Windows 7 (the oldest version of Windows still supported by Microsoft) includes a Windows Update for the .NET Framework v4.6.1 categorized as an "Important" update. I have not confirmed with Windows 8, but I suspect it, too, includes a similar update. Windows 10 comes with .NET 4.6 to start with. That means that any up-to-date supported machine today will be able to run apps targeting any .NET version up to and including 4.6. I recognize that there may be other reasons to continue targeting an older .NET version, but I bring this up just in case the concern is support on client workstations.

Afternoon all,
I had been using the Visual Studio 2022 Preview. Recently I decided to switch to the Release version. I uninstalled VS2022 Preview and installed the 2022 Community Release.
The install runs fine and completes with no issues. However when trying to run VS2022 It comes up with the error attached below.
From my talks with MS found at https://developercommunity.visualstudio.com/t/Unable-to-launch-VS-Comunity-2022-after/1596301?entry=myfeedback&viewtype=all It appears VS2022 Community should be running version 17.0 of the .Threading DLL. However no matter what I have tried it refuses to load.
I have run the uninstaller with -F. Re-installed several times.
Attempted to install 17.0 to the GAC but this does not change the outcome
As per the post on the developer community pretty much everything short of re-installing windows (Which I am 100% trying to avoid)
I ran the FusionLog viewer (Attached) and it looks like there is something re-binding this to the 17.1 .threading version however I know very little about how this works and where I might find a solution, Hence, I am here :). Although my post on the DeveloperCommunity is still active I'm hoping a resolution here maybe faster!
Thank you!
I have this error too, and its becouse you dont have defined startup project.
Right click on your startup project and choose "set as startup project".
Actually the above is incorrect, you can't even get to the startup screen.
The correct answer is you need to remove the V15 version of the dll from the GAC. Instructions from MS can be found here.
I'm having trouble installing Visual Studio 2012. When I run the installer I get the message:
Microsoft .NET Framework required for Microsoft Visual Studio Professional 2012 setup
The first time I got this message, I clicked to install. It loaded some stuff but it didn't look like it installed anything. I ran the installer for VS 2012 again and I get the same message but now without any buttons to click on. Is there any solution to this?
What happened before
I had VS 2012 already up and working. I left it alone for quite a while until I decided I wanted to do some programming again. Starting the application resulted suddenly in an error:
Cannot find one or more components. Please reinstall the application.
After searching for a couple of hours I couldn't resolve the problem so I did as it asked and reinstalled VS, but I got the same error again. Then I tried to remove every single application VS installs as indicated by this list and any program that had a similar name. I also removed all .NET versions and C++ redistributables. Now I can't install VS anymore and some games and gadgets are now broken.
And I always, always, always forget the existence of system restore. I doubt my oldest system restore is old enough. This is going to be my last resort.
What I tried
Search for a .NET installation in the control panel, it's not present after clicking the install button on the prompt of the VS 2012 installer.
Reinstall .NET 4.5 using this installer. It installs correctly, but the problem persists.
Turning .NET 3.5.1 off from windows features and install it manually. This fails for an unknown reason (error code -2145124329, which seems undefined). Just turning it off doesn't work either.
I'm trying to install Visual Studio 2005 on a Windows 7 box but am repeatedly getting the same error. When I run the installer it starts to run then pops up with a message saying:
"A problem has been encountered while loading the setup components. Canceling setup."
Various suggestions has said that maybe the install is corrupted so I downloaded a fresh copy of the ISO from MSDN today, same issue. Another suggestion is that installing from the ISO may be the issue so I extracted the contents of the ISO to a folder on my HDD, same issue. I have also tried running the files as administrator and in XP compatability mode, same issue.
Searching for this issue the most common responses I've found have been about installing SP1, however I cannot get the base product to install and therefore cannot apply SP1.
Does anyone have any further suggestions as to what I can do to fix this issue and get VS2005 installed? If anyone wants any log files of any variety I am happy to supply so long as you tell me where to look as I'm not sure.
As for why I am using VS2005 and not a newer product, it is required for the ongoing support and maintenance of some older applications we manage. These cannot be easily migrated to a newer version of Visual Studio without some considerable investment of time and that would probably be longer than the time it will take to develop newer, replacement applications (which is currently in progress). Until the new applications are available though we need to maintain an environment to use.
Did you try running setup.exe in compatibility mode with Windows XP? Some discussion here on how to do this.
Another alternative since you alluded to having an MSDN subscription. Download Windows XP and install it into a VM. (If HyperV isn't already in installed with your Win7, you can add it from Control Panel->Programs&Features->Turn Windows Features on/off). Then install VS2005 from there.
I have a C# console app in Visual Studio 2010 that I can run just fine. When I attempt to run the process in debug mode, I am presented with the following error:
I have tried searching for any information, but I haven't been able to find anything. Can anyone provide clues as to why I can't run this with the debugger?
EDIT: I should clarify that I have been able to successfully debug a console app previously, this is a new situation.
From what I can tell when I'm able to reproduce this error, it is caused by being in the middle of installing Windows updates. So, running updates, then postponing a reboot, then attempting to debug code is what was putting me in this broken state.
I had this issue once and it was caused by an pending Windows Update on the Server where the process was running, which I wanted to attach.
I encountered the same issue. It happened to me when I attempted to attach to a process for debugging purposes. At the time I had postponed a pending windows update.
Everything started working fine after I restarted my computer and allowed the update to take place.
Additional notes: I had recently updated to Visual Studio 2010 Ultimate and installed its Service Pack 1.
I had this when I installed .NET 4.6 for Visual Studio 2013.
In this particular case, restarting Visual Studio 2013 solved the problem.
I have finally solved this!
It seemed to have happened after I updated my Windows 7. One of my files must have been out of date.
The fix: Install VS 2010 Service Pack 1
Worked correctly right after I installed. Hitting breakpoints and everything!
Hope this works for you too!
I also updated to Service Pack 1, and made sure Windows updates were up to date, but I was still having the same issue:
"The Version of CLR.dll in the target does not match the one mscordacwks.dll was built for."
Microsoft closed this issue on connect.microsoft.com as not reproducible... Unforgivable, irresponsible support system!!
But on social.msdn.com I was directed to upgrade through this link, and this has resolved the problem in my machine ( Win7,VS2010,target 4.0)
Hope it helps.
Simply. Restarting Visual Studio solved the problem in my case.
I had VS 2010 SP1 for ages and had rebooted many times. There wasn't any windows update in progress either. I closed all my VS 2010 IDEs and then opened them, and the problem was gone.
This happens, when you do a WINDOWS UPDATE and haven't rebooted your system and the update isn't compatible with VISUAL STUDIO. So in order to solve this, just do an update on VISUAL STUDIO to latest. That should FIX it
I had this weird issue after installing .net framework 4.5, when using .net 4 for my project.
updating VS 2010 service pack didn't solve this, only removal of .net 4.5 and 4, and then reinstalling .net 4 only.
I have VS2013 on Win7 and restarting VS worked for me. Seems it is a VS/CLR bug.
I currently have Visual Studio v2003, v2005, v2008 installed on my system. Things work fine...no issues.
I now have to install Visual Studio 2010 on my system and just wanted to know if anyone has a setup like mine or knows if there are any potential issues with so many versions existing on a system.
Really don't have a choice to remove older versions as we have a lot of legacy products written in these old versions and we are not upgrading them to new versions, only doing bug fixes on them.
Any ideas?
Thanks!
VS2010 supports targeting on multiple versions of .NET Framework (i.e. 2.0 or later), which mean it is designed to support the projects that were built with VS2005/VS2008 so-called backward-compatibility.
So I think no conflict here between these versions,
I've found a nice Myths and facts about VS 2005/2008/2010, check out this link here: http://msdn.microsoft.com/en-gb/ee679805.aspx
It should work.
I have vs2003, vs2008 and vs2010 installed and I see no issue (but vs2010 is not yet used for production code).
M.
All these versions of Visual Studio are independent.
You should have no problem (other than lack of disk space!) installing VS2010 as well.
Just make sure you install the service pack as well.
They cohabitate fine, I have a similar setup myself.
You should at least push for migrating away from 2003 and 2005 though, they use some pretty old technology, and pretty much everyone these days has .net 3.5 on their systems.
If you are able to use VS 2010 I would highly recommend you do for all new projects - even if you have to target an earlier version of .NET framework.
Keep the old versions of VS installed only for maintenance of projects that cannot be migrated to VS 2010 version.
By the way, the migration to VS 2010 is often very trivial and well worth an hour or two of effort!
