Blank screen

Version 5.64 will not install on my machine. I am running windowns 10 and a new Dell laptop. Running the install program ends up with a blank page after an hour of waiting for completion.

I am seeing the same thing with version 565 of CCleaner.

running windows 10 (latest updates) on a Dell XPS Tower.

First check if you have compatibility mode with Windows 7 set, that will result in a blank screen in the installer such as you describe.

See the second part of this post:

Windows 7 does not have the required up to date technology to run the latest 'Standard' installer.

If you are not sure then try download the 'Slim' installer from here: https://www.piriform.com/ccleaner/builds

The Slim installer does not contain the bit that Win7 can't process and so the slim installer still works on Win7, and Win7 compitability mode.

If that still doesn't help then please come back and tell us which antivirus you are using.
