Urgent - Office Installation failed with Errorcode 1603 at ProPlusWW.msi

Hello together,

the installation of Office Professional Plus 2010 failed with Error 1603 on my new notebook running Win7 x64. The Setup only says "Microsoft Office Professional Plus 2010 hat bei der Installation einen Fehler festgestellt". I found in the installation log from %TEMP% this error:

Error: Failed to install product: C:\MSOCache\All Users\{20140000-0011-0000-0000-0000000FF1CE}-C\ProPlusWW.msi ErrorCode: 1603(0x643).

Google delivers some results addicted to this error, the most of them are HowTos to delete an old office installation. I've checked this, but nothing was found. I've tried to install as an new User, set permissions to Install- and Windows-Folder again - nothing helps. My last trys are downloading the setup from http://care.dlservice.microsoft.com again and trying to install this new setup directly after a new Win7 x64 setup with SP1, but without any updates. But the same error occurs. :-(

Who can help me? I'm at the end with my knowledge... Thanks alot. Sry for my probably bad english...
