Dont know much about computers, please can you help. I downloaded CC v5.0 from offical site, when i run it to install, vista stops it running (i have Symantec AV and this says nothing) how can i install CC. I wanted to buy it but am so glad i tried the trial first, if i can fix this i can then go ahead and purchase. Many Thanks my friend.
what, if any, is the error message you are getting?
what was the official site you got it from?
here is the download page you should use; https://www.piriform.com/ccleaner/builds
Also, v5.01 is out.
