SOS debugging extension on 64bit Applications

Recently I got into a problem running the SOS on a 64bit Virtual Machine. Visual Studio gave the following message :

Microsoft Visual Studio
Error while trying to run project: Unable to start program '<app path>'.

The debugger does not support debugging managed and native code at the same time on this platform.

Binging’ around I found that there is a known issue in Visual Studio 2008 Mixed Mode Debugging for 64bit Applications. Since to run the SOS we have to ‘Enable unmanaged code debugging’, hence the issue.
The only way I could make it working with VS 2008 was by changing the Platform Configuration to x86.
