"GenerateResource" task CLR2 runtime error

Question

My app keeps getting this error (I'm using VS 2013, VB.NET, and Windows 8.1, by the way):

Could not run the "GenerateResource" task because MSBuild could not create or connect to a task host with runtime "CLR2" and architecture "x86". Please ensure that (1) the requested runtime and/or architecture are available on the machine, and (2) that the required executable "C:\Program Files (x86)\MSBuild\12.0\bin\MSBuildTaskHost.exe" exists and can be run.

The app is for .NET 3.5 (3.5 and lower versions get me this error). I try to run the app again. Sometimes, it works; sometimes, the error comes back.

I already tried looking up for answers at Google and the answer they gave me turned out to be: "Your build's username is too long" (they said that 20 characters or more cause the error), but it's not true. My user name is 5 characters only. Anyway, I don't think my build's username's length has anything to do with it; it makes no sense.

Does anyone know what is wrong with 3.5 and lower versions? Thank you.

None of the answers in this worked for me. I had to run Visual Studio as admin. Hope this helps someone in the future!

Adding this in each project is a cumbersome task. So you can set it in the environment variables.

Click Start>> Right-click Computer >> Properties >> Advanced system settings >> Click Environment Variables button to open the dialog, then under the System variables section, click New… button, type the Variable name = DISABLEOUTOFPROCTASKHOST, and type the Variable value = 1, then click Ok.

I tried opening an old VS2010 vb project inside VS2013 recently and just ran into this problem. I got around it this way:

1. I went to the vb project's properties page
2. I clicked the "Debug" tab
3. In the "Enable Debugers" section, I saw that the "(x) Enable the Visual Studio hosting process" checkbox was already checked.
4. I tried un-checking the "( ) Enable the Visual Studio hosting process" option
5. I saved these changes (Ctrl+S)
6. I then checked the "(x) Enable the Visual Studio hosting process" checkbox once more
7. I saved these changes (Ctrl+S)

My next re-build of the project was then successful.

Luckily, I was able to observe how the .vbproj file changed in my version control, and saw that it added the following line into it (which was not there before, despite the checkbox already being set initially):

<UseVSHostingProcess>true</UseVSHostingProcess>

Answer 5

I encountered this error when trying to build a sample solution that was included in some software that was installed under C:\Program Files\. Visual Studio prompted me to restart with elevated privileges (as it does when opening a solution in a "secure" location), however the build failed with the OP's error message.

Copying the solution to a "normal" folder (e.g. C:\Temp) solved it for me.
