adobe_oobelib.dll error while starting Windows

Hello!

While booting the system I get the following error message:

Starting the Crative Cloud i usually get this error message:

O.K. - no Problem - download the new Version and install it new. But doing this i will get the same Message: The installation routine stops after a few seconds and brings just the abowe shown message.

In a comparable post to the adobe_oobelib.dll problem it was recommended to delete all files in the folder ...\local\adobe\oobe. I did so but nothing changed.

When starting Photoshop or LIghtroom nothing happens - these applications do not start and no Errormessage is presented.

I would apprechiate if you can give me further advice on how to fix this. Thanks in advance.

Best regards,

Friedrich-Wilhelm
