How to install debugging tools for Windows 32-bit side-by-side with 64-bit on a 64-bit OS?


I have a 64 bits Windows 2008R2 VM, where I installed Debugging tools for Windows 64 bits from the SDK. Now I wish to install the 32 bits and even downloaded the respective ISO - GRMSDK_EN_DVD.iso from

However, the damn thing thinks there is nothing to install, because the 64 bits is already installed.

How can I still install it?


OK, I uninstalled the 64 bits version. Now, it fails to install with this lovely message:

Setup could not find the file WinSDK_amd64\WinSDK_amd64.msi at any of the specified source locations E:\Setup

Microsoft support site claims that I am probably trying to install a wrong architecture. But the ISO file name is GRMSDK_EN_DVD.iso and says it is for x86.

If I cannot install x86 on a 64 bits OS, then how do I get the 32 bits windbg installed on my 64 bits OS ?

Please, help anyone.
