Try the CCleaner Slim installer instead to see if that works:

Someone else reported the same error on Wednesday.

That was caused by BitDefender blocking the 'Standard' installation. ( That 'Fault mode name' atcuf32.dll is a BitDefender file/filter).
It appears that BitDefender does not like v5.63 for some reason.

That member used the 'Slim' installer to sucessfully install CCleaner v5.63.

I was the one who reported the problem the other day. I thought the problem might be Windows 7, but I use BitDefender too so this is obviously the cause. Unfortunately, I do  not know what the "Slim" installer is. Can I download it from the internet?

Look for the slim build (last one in list)

I was actually thinking of MonkeyTech's posts here, which reported the same atcuf32.dll error as above.

However if you also have BitDefender then yours could well be the same issue and downloading/installing the Slim version should also work for you.
