Hi
Weird reaction of the upgrade routine...
I'm using the last version of Win10 64b with e-set's nod32 and malware bytes protection tools.
The upgrade process fails completely at deleting ccleaner.exe and ccleaner64.exe, resulting in the install routine to propose to cancel, retry or ignore. Whatever the choice, it's a wrong one.
Such routine should never fail...
I had to change the default installation path, but what about the next update?
This is not the first time, and it's the only program that has this problem.
