I've currently got Windows 7 Pro installed on a system at work and am trying to install Windows Embedded 8, but I'm getting an error during setup. I've downloaded the rar files from the official Microsoft site, used their .exe to generate an .iso file, and have mounted it to the system using VirtualCloneDrive.

Once mounted, I launch the setup.exe and almost immediately get an error that says:

"Windows Setup failed to register Embedded COM DLLs. See setup log files under [C:\$WINDOWS.~BT\Sources\Panther] for details.

This log file in turn says:

Error [0x060755] IBS Callback_Embedded_ComRegistration: Failed to register EmbeddedMmi.dll under C:\$WINDOWS.~BT\Sources with return code 0x3 from regsvr32 .

I'm in a hurry to get this up and running. Anyone have any ideas?
