I have downloaded the ccsetup573.exe, 29154 kb size. It fails with the error, installer integrity check has failed.
I uninstalled the version i had running, rebooted, downloaded the ccsetup570 and that installed, then i went to have CC download the newest version 573 and tried that and it fails.
I have tried this over and over and still fails. i have Windows Defender turned off and still no go.
Same issue. Haven't installed a new version of CCleaner for a while so not sure if it was something I did or windows 10 just being stupid and flagging this file/program.
