ccleaner 525 will not install

I'm running windows 10 version 1607 Build 14393.576. Ccleaner v5.24.5841 (64-bit) is running OK, but when I try to update using CCsetup525.exe, it does not work.

If i just run ccsetup525.exe I get a splash screen with "This app can't run on your PC. to find a version for your PC, check with the software publisher."

If I run ccsetup.exe as administrator, I get the usual User Account Control pop up asking if I want to allow program from unknown publisher etc. After clicking "YES", I get an error popup

C:\ccsetup525.exe

Windows cannot find 'C:\ccsetup525'. Make sure you've typed the name correctly, then try again.

Note this happens wherever I try and run CCsetup525 from.

Any ideas what is going on here?

Uninstall CCleaner 5.24 and then install build 5.25 from here
