MSBuild does not contain a value for the "VCTargetsPath" property

I recently installed the Visual Studio 11 Developer Preview to try it out, and now my VS 2010 projects won't open. Instead, I get the following error message:

MSBuild does not contain a value for the "VCTargetsPath" property

I found someone that had reported the issue here on Connect, and the response from Microsoft was:

Hi Afshin,

Thanks for the feedback. The issue you ran into is fixed for the next public release Visual Studio.

Fantastic. So how do I restore VCTargetsPath so my projects will work again?

"VCTargetsPath is a toolset property that is defined in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSBuild\ToolsVersions\4.0. "

I browsed to the VCTargetPath value in the registry and it has the value:

$(MSBuildExtensionsPath32)\Microsoft.Cpp\v4.0\

Not sure where to go from here. Any suggestions?

It seems reasonable that the solution Gavin Pugh gave would fix the problem, though I didn't try it. I too ran into this problem after uninstalling the Developer Preview of VS11. I think I know what is really wrong though.

Mladen Jankovic was on the right track. One of the follow two (necessary) registry keys was missing on my machine:

• HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSBuild\ToolsVersions\4.0
  • Key Name: VCTargetsPath
  • Type: REG_SZ
  • Value: $(MSBuildExtensionsPath32)\Microsoft.Cpp\v4.0\
• HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\MSBuild\ToolsVersions\4.0
  • Key Name: VCTargetsPath
  • Type: REG_SZ
  • Value: $(MSBuildExtensionsPath32)\Microsoft.Cpp\v4.0\

(You can edit registry keys in Windows by typing +R+regedit+Enter)

For me, the second value I listed above was the one that was missing. After I added it, I was able to work with my project again.

Here's the thing that did trick for me:

Change registry value named DefaultToolsVersion located in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSBuild\4.0 from 2.0 to 4.0. Do the same thing in Wow6432Node too.

The registry editing method suggested by "Mladen Jankovic" didn't work for me.

I just ran a repair on Visual Studio 2010 (run the setup.exe on the VS2010 install disc, or invoke the 'uninstall' via Control Panel->Programs). It did the trick for me.

You also should run the SP1 install again.

For what it's worth, my 'add-ins' (including Incredibuild) behaved fine after this. They didn't need to be reinstalled or repaired. My settings/window/debugger placement also was retained.

Apparently this issue only presents itself if you uninstall the Developer Preview of VS11: http://www.gamefromscratch.com/post/2011/12/15/Do-not-remove-Visual-Studio-2011-developer-preview!.aspx
