Hi,
After ccsetup607_slim.exe installation on Win10 (fully updated) CCleaner doesn't start.
In process viewer CCleaner shows up and immidiately shuts down without showing any GUI.
This bug happends sync v6.00
What you describe can have a couple of causes.
I think you are probably seeing a known bug that can happen if you install CCleaner as a non-admin user.
It's a permissions bug and they are working to fix it, but we have a workround.
Install it again and this time when the installer wants to open CCleaner leave it ticked, click Finish and let CCleaner open.
That does then set the required permissions for a non-admin user.
CCleaner will (should) then work normally when you open it from the desktop.
If that doesn't fix it for you then please come back and tell us if you have an Antivirus installed, what it is and what version number it is.
Thanks a lot. It worked.
