I'm running windows 7, 64-bit and I can't get the free version to even install. I've been using earlier versions without an issue. Is the current v.5 release a Beta version? Don't recall there being any statement of this in the e-mail I received telling me it was available to download.
Could this failure be somehow related to the Windows Update KB3000850 ?
I installed it 10 hours before the CCleaner v.5 update.
Mulaw,
Run "Disk Cleanup" in Administrative Tools. Right click on Disk Cleanup and select "Run as Adminstrator". Check mark all the items that Disk Cleanup displays to clean. One of these items should be Windows Update Cleanup and it will be many megabytes in size. The cleaning process may take an hour or so if you have never done this before or because of the huge update of KB3000850. After Disk Cleanup is completed, try running CCleaner again.
I'm running V5.0 on more than one 8.1.1 x64 Professional systems and also on Windows 10 Technical Preview with no problems. Can you identify which cleaning component is causing the hang? Uncheck a block of say 5 items at a time and run the CCleaner to see if it completes. I would start on the Applications tab first. Once you isolate which cleaning item is causing the hang, then perhaps the developers can find the cause. There may be a file on your system that is corrupt that is causing the issue.
You could also see if starting CCleaner via "Run as Administrator" with all Monitoring turned OFF via Options>Monitoring helps.
I'm on windows 8.1 Single Language Spanish. I had the same problems as described above. When I re-installed CCleaner V5.00.5050 (not selecting Spanish) but yes selecting English: it worked.!!!
