Unable to remove product with code yada yada

Hello postini!!
Here we are, another new problem uninstalling Exchange 2007! 😦
Running setup.com /uninstall, see what happened:

C:\Program Files\Microsoft\Exchange Server\Bin>Setup /mode:uninstall

 Unable to remove product with code 24b2c164-de66-44fe-b468-a46d9d5e6b31. Fa
 tal error during installation. Error code is 1603.
The Exchange Server Setup operation did not complete. For more information, visi
 t http://support.microsoft.com and enter the Error ID.
Exchange Server setup encountered an error.

ARGHH!!! WHAT THE HELL IS THIS?!?!?!?
Googling around and trying, I found this solution:
Go to Exchange installation directory (usually C:\Program Files\Microsoft\Exchange Server) and propagate the directory inheritable security permissions.

From my experience, this problem happened in conjunction with this one:
“Process execution failed with exit code 5”
that you can solve looking at the uninstallation log (usually placed here: C:\ExchangeSetupLogs\ExchangeSetup.log) an registering the dll that raises the error.

See ya!
