Tools Version

Question

Hi.
First of all, I didn't really know where to post this, and I'm desperate for some help..

I got the Visual Studio 2008 trial edit, and everytime I create/load a project I get this error:

The tools version "3.5" is unrecognized.

Please help me.

By the way, it worked before.. I don't know what "destroyed" it..

Hello,

 

We provide you with several suggestions here:

1. Please check if your .NET Framework 3.5 has already been installed correctly.

If that’s the case, please download it here.

You could check it by looking at Add and Remove Program in the Control Panel.

2. Please check if these registry keys are exist:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSBuild]

 

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSBuild\3.5]  “DefaultToolsVersion” = “2.0”

 

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSBuild\ToolsVersions]

 

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSBuild\ToolsVersions\2.0]

“MSBuildToolsPath” = “C:\\Windows\\Microsoft.NET\\Framework\\v2.0.50727\\”

 

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSBuild\ToolsVersions\3.5]

“MSBuildToolsPath” = “C:\\Windows\\Microsoft.NET\\Framework\\v3.5\\”

 

Please try to check and see if they are missing.

If that’s the case, please add them after a suitable backup of your register, also, please take a notice that the value of the  variables above are based on the directory of your system driver.

 

Otherwise, I’d like to ask a few questions:

1.       What’s your Operating System?

2.       What kind of project are you loading?

3.       Could you please describe the error message in more detail ?

 

Hoping that could help!

Best regards,

Hi Roahn Luo,

I met the same problem, and solved it with your solutions.
You r very great. It's surely missing those register keys.

Thank you very much.

But I can't understand how it's happen.
