I'm trying to apply an update and I'm getting this error, followed by C:/Program Files/CCleaner/CCleaner.exe.
I've used this program for years and I'm completely stumped. I tried some of the fixes I found by Googling but nothing worked.
The account I'm using is an administrator account, but I right clicked the installer and selected "Run as administrator."
I followed the directions about going to C:/Program Files/CCleaner -- right click/Properties/Users/Full Control.
I still can't update the program.
