Dte.olb could not be loaded
After reinstalling my pc, (had to after I tried to crack something (I steer clear of this now :)) I got the following error when trying to open a newly installed Visual Studio.NET:
“Dte.olb could not be loaded. Please re-run setup and repair your installation”
So I repaired my installation and after it I still got the error. I found the solution on Shannon Shang's blog: Basically this COM object didn't register succesfully, so after registering it again it worked perfectly :D
regsvr32.exe "c:\Program Files\Common Files\Microsoft Shared\MSEnv\dte.olb"
