VS2010 : MSVSMON.exe failed to start

visual studio 2010

I am trying to migrate an old VS2005 application to VS2010. I am trying to debug that application, but after I cleaned the project then tried to build it, MSVSMON.exe failed to start and an error message appears.

Any ideas? Googling around I find that I am trying to debug a 32bit app in a 64bit debbuger?
Cleaning the project does not fix that problem?

In Regedit, navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa

Right-click Lsa and create a new DWORD

value Name it DisableLoopbackCheck Set its value to 1

Reboot (instead, I killed the msvsmon.exe process and restarted Visual Studio)

Check also the comment of soandos I use that also!

So many years and windows still uses regedit!
