Visual Studio setup cannot run in compatibility mode in VS2010

The solution from Dluk, posted for the Beta2 Version of Visual Studio 2010 on 11/10/2009 and worked for me with the **released** version was…:

Got it!
1. Rename following registry key before install (e.g. add _ to the name):
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\setup.exe\HighVersionLie-{6B64DE21-0F4C-4479-9D6C-0FBCA496BCDC}
2. Install VS2010
3. Return key name back.
