    Hello, I run Windows 7 on my iMAC via Parallells without any problems normally. It works e.g. fine to run the Windows Office programs. But I run into problems when I try to run Windows Movie Maker.

    I get the instruction to run dxdiag.exe to verify my DDI-version.

    And then I get the following message from Windows:

    '"The file prl_umdd.dll is not digitally signed, which means that it has not been tested by Microsoft Windows

    Hardware Quality Labs (WHQL). You can maybe get a WHQL-signed file from the hardware supplyer."

    Is this a wellknown problem among mac-users who run Windows via Parallels?

    Any suggestion what I should do?
