Google. Here's the fix:
Download "subinacl" here. This is a command-line tool that enables administrators to obtain security information about files, registry keys, and services, and transfer this information from user to user, from local or global group to group, and from domain to domain.
After installing subinacl.exe (it will be in the C:\Program Files\Windows Resource Kits\Tools folder.), drop to a command prompt and run the following batch file, which you have saved in the same folder with the filename "FIX.bat":
subinacl /subkeyreg HKEY_CLASSES_ROOT\VisualStudio.vbproj.9.0 /grant=administrators=f
subinacl /subkeyreg HKEY_CLASSES_ROOT\VisualStudio.vbproj.9.0 /grant=users=f
subinacl /subkeyreg HKEY_CLASSES_ROOT\VisualStudio.vbproj.9.0 /grant=system=f
subinacl /subkeyreg HKEY_CLASSES_ROOT\VisualStudio.csproj.9.0 /grant=administrators=f
subinacl /subkeyreg HKEY_CLASSES_ROOT\VisualStudio.csproj.9.0 /grant=users=f
subinacl /subkeyreg HKEY_CLASSES_ROOT\VisualStudio.csproj.9.0 /grant=system=f
BAM! All fixed! Have fun.
Thanks if I helped.
PS: PM me if you want the link so you can download the program. I cannot post it here.
