'Machine Debug Manager' error when installing Visual Studio 2008 SP1 on Windows 7 machine

When installing Visual Studio 2008 SP1 on a Windows 7 machine, you may encounter a message prompt asking to close the 'Machine Debug Manager' process. This can be really irritating and end up the installation to run indefinitely.

To overcome this problem, try killing the mdm.exe process from the Task Manager. Hope this simple workaround works for you.
