Ok, I understand now...
First uninstall version 8.7 from your PC
(through Control Panel), restart PC and after that install version 8.8 (during installation, choose "perpetual" license) and again restart... after that apply Patch 5.
You'll get pass. for Patch 5 ( v8.8 ) via PM in the next few minutes.
After that, finally, check is everything Ok via "About" button
(you have instructions how to do that, above). If you want to be sure, that everything is Ok, provide us screenshot.
cya later,
S.
