Hello,
So my apologies if this is in the incorrect section, however I am a bit flummoxed as to why CCleaner has suddenly stopped opening and won't install when I removed it. I have performed a full virus scan with Kaspersky and checked the processes running on my copy of Windows 7 x64. When I boot into safe mood I was able to install CCleaner and had luck in opening it and performing a registry clean, but when I attempted to scan it ran then crashed (displaying am message that it has stopped working). When I boot normally it just opens for a second, immediately freezes, and then states that the application has stopped working.
The odd thing is that it was working fine before I recently installed some drivers for an Epson scanner, so it's a theory but I have a hard time imagining it as the cause. Anybody out there with a better idea than I?
Thanks in advance to all who reply!
EDIT - SOLVED:
I had previously performed a system restore but when I performed a system restore to a date that was prior to install of the drivers for my Epson V600 Scanner I was able to regain full functionality of CCleaner. I am not sure what is to blame (Epson or an update), but obviously there was some sort of confliction that existed. My appreciation to all those who offered help. Hopefully anyone experiencing similar issues is able to use either my solution or the solutions below to their benefit.
