Uninstallation ABAP Trial Version

Hello,

I would like to uninstall the 7.01 ABAP Trial Version, but when I call the function for the uninstallation I receive the following error message:

Errors occurred during the uninstallation.

null

I've already checked the LOG file and it tells me that there is an 'java.lang.NullPointerException'

I've already searched the SDN but I couldn't find a solution.

Looking forward for some suggestions.

Best Regards

Frank
