I had Uninstall my Visual Paradigm Suite 5 two days ago!
Now when i try to reinstall it, a NullPointerException is thrown so i can’t install it;
The installator also say to look in a log file for more o*information;
Can tou please help me!

Dear user,

Thank you for your interest in our product. May I know at which phrase of installation the exception showed? Could you copy the log to me? You said that the installer told you to look into a log file for information. Could you send that log file to me? Thank you.

Best regards,
