Installing cccleaner

I keep getting this message when I try to install cccleaner

"Error opening file for writing

[path to file in C programme Files]

Then I get three options

Abort

Retry

Ignore"

Any suggestions?

Thanks

Mike

have you check to see if the process is running???

Few suggestions suggest a previous version could be running. check task manager for ccleaner.exe

Also try re-downloading it
