CCleaner v5.20 Setup won't install.
New interface exe goes to one green bar than stops & freezes. Have to use Task Manager to end task.
Portable v5.20 is fine.
See if anything in here helps:
Is named ccsetup520.exe
DId not Open or Run, Saved.
Disabled Anti Virus.
Verified in Task Manager.
Ran as Administrator, Safe Mode, reboot.
Downloaded multiple times from Chrome, Firefox, Internet Explorer, Edge.
Portable opens fine, prefer capabilities of installed version.
Cleaned Temporary Internet Files.
Been using for over 10 years, never had a problem before.
Notice new 5.20 version has brand new installer interface!
Press Blue Install, immediately goes to CCleaner v.520 Setup interface with one green bar, then nothing else happens.
Fixed, by rebooting computer. Windows 10.
Engineering/Tech should look it why new interface install, needs a reboot.
Fixed, by rebooting computer.
That was one of the solutions in the link I provided in post #2.
