Error opening file for writing (CCleaner 5.60 update)

Pop up message trying to update CCleaner 560.

"Error opening file for writing:

C:\Program Files\CCleaner\CCleaner64.exe

Click Abort to stop the installation,

Retry to try again, or

Ignore to skip this file"

I have had this before on earlier updates and never found a work around.

Thank you Nergal for a quick & easy solution.
