Error Opening File

While updating to CCleaner v5.61, on each of my four attempts, I get this message:

Error opening file for writing:

C:\ProgramFiles\CCleaner\CCleaner64.exe

So, I had to abort each time. I run Windows 10 using the Chrome Browser.

This is the first time ever that I have had an issue updating (many years). This is the free version download for my personal use.

Thanks,

Tony
