Can't update 550 pro

Everytime I try to update to 550 I get an error telling me Error opening file for writing: C:\Program Files\CCleaner\CCleaner64.exe, then if I ignore I get the same message but with branding.dll.

I've quit my Malwarebytes and halted my Avast, I'm not sure what to do next.

Need help please :)

It sounds like ccleaner is still running (maybe smart cleaning in the system tray). Check task manager for any ccleaner remnants.

Thanks a lot, it's updated and running no problem :)

Glad you got it sorted

Yay! All fixed now! Many thanks
