HELP Tried the latest update and could not install it and could nor run previous version installed. I keep getting this message "Error opening file for writing" Tried uninstalling with windows and I thought it worked, but not. I am running a windows 10 PC. Previous version 5.3 worked fine, update was 5.4.Tried to remove from windows program files but wouldn't let me. I was running the free version but I also tried to install the paid Pro version with the same results. What do I do now?
I have uninstalled my 5.33 version of CCleaner and updated to 5.34, as a new update was shown to be available. I had no problems with my 5.33 at this time. I used RevoUninstaller to remove CCleaner. So I then went to the Piriform website and installed latest CCleaner 5.34 and my Malwarbytes found trojan.nyetya and quarantined it. I uninstalled 2 more times and reinstalled and same thing happening. I even tried your link to the latest version and still get trojan.nyetya getting quarantined. Now what?
