I had the same problem trying to uninstall Exchange 2007 after Exchange 2010 installation. I have noticed from the Exchangesetuplogs that the setup tried to register DiagnosticCmdletController.dll in x86 folder although a 64-bit platform. I switched the dll in the X86 and AMD64 folders until the setup has not set the correct path. Then I registered the DiagnosticCmdletController.dll and the uninstallation was successful.
