Apply the following fix. Make sure these keys are present in the registry. If not present add it. This should resolve this issue. [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\” Ref: http://execucode.com/2009/01/08/the-tools-version-35-is-unrecognized-error-on-visual-studio-2008-startup/ Thanks -- Vijaya Kadiyala www.DotNetVJ.Com

Yeah you can always remove all the VS 2008 related products going to add remove programs you can remove it, but try installing the Framework 3.5 SP1 as a last option. Thanks, Lisa
