CCleaner doesn't launch

Basically: Installed CCleaner > After the setup is complete, I checked the "Run CCleaner" box so I can use it already > Used it > Closed it.

After that, everytime I try to open it (double clicking the icon) nothing happens.

I tried unchecking the "Automatically check for updates for CCleaner" and launching it in Safe mode, still no success. Seems to me like the only way I can use CCleaner is installing it over and over again.

What operating system?

What security software do you run?

Don't use the same installer over and over. To eliminate installer corruption as a cause, uninstall what you have, reboot, then download and install the slim build from here.

When you say after install 'I ticked the Run Ccleaner box', as far as I remember it is pre-ticked anyway (may be wrong!)

Thanks for the reply. OS: Win 8.1 64bits, I'm using AVG and Avast.

It still doesn't launch. I just tried uninstalling>rebooting>installing the slim build, but the problem remains.

Oh and yes, the "Run CCleaner" box is pre-ticked :)

any reason why you are running 2 AV's?

are they just the anti-virus versions or the internet security version?

have you tried the portable build?

No reason(Is it bad?). They are the anti-virus versions.

Wow Thanks! The portable build seems to launch everytime. Solved.

No reason(Is it bad?). They are the anti-virus versions.
