ccleaner does not start

Good morning
I have Windows Vista Ultimate and when I click on Ccleaner to start the program I get the message out ccleaner does not respond after 10-20 secondi.
After about 1 minute it opens but with difficulty.
I tried to uninstall and reinstall the program but continues to open up to fatigue and also scan to clean and very slow
Which checks can I do to speed up the opening of the program ?
Tank you

Uninstall CCleaner and reboot.

Install the slim build from here

https://www.piriform.com/ccleaner/builds

Is that better?

(What antivirus do you use?)

microsoft security essential

What's different from the normal version slim buil

The only difference is in the installers, the Slim build installer does not include the Google 3rd party programs.

Also boot into Safe Mode and then run ccleaner ( just as a test, one time only)

See if that helps.

Ciao
I installed ccleaner slim looks like things are getting better It is a bit 'more' fast but especially when I click it opens without the message out that I can not answer ccleaner
One thing when I start the pc in safe mode seems to me the same icon ccleaner on the screen to be able to click on it and scan with cclaner. Is so ?

If you're referring to the desktop shortcut then yes in safe mode you can use it to open CCleaner.
