CCleaner for Windows version specific questions
We no longer support old versions like CCleaner v5.63. CCleaner for Windows gets updated to newer versions to fix bugs and to improve its features and functions. It's possible that any specific issues you are experiencing with a specific version may have been fixed in a later update, so we highly recommend updating your software to the latest version of CCleaner to see if that resolves the problem first. However, we can always help if you need further assistance.
