bueno yo lo arregle de otra forma, en la parte de abajo colocare el post que encontre y con el cual lo resolví, gracias por contestar.
The company I work for uses a standard image for all our computers, since I last posted, I received a new computer, never had Visual Studio beta installed, went straight to the production release of Visual Studio 2010 and encountered the exact same problem.
There were no older 4.0.X versions of the .net framework to be found, but the following link worked for me. Notice that there is a workaround tab on the page displayed.
The link:
http://connect.microsoft.com/VisualS...iletracker-dll
I am also reproducing the instructions from that link to save some effort for those who have read this far.
Find the file: C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\Micr osoft.Common.Targets
Locate the <GenerateResource> tag at Line 1835 and delete the attributes TrackFileAccess and TrackerLogDirectory
