system locks up

I downloaded the update today and the system starts analyse but stops at 45%. when you cancel it locks up and you have to ctrl/alt / delete , to shut down the program. Using windows 10. I have removed and reloaded , but still the same.

Any ideas.

G'day John,

what does is say it is cleaning at the 45% stage, next to the spinning "I'm thinking" wheel?

hi. system temporary files

if you haven't run CC for a while, the temp files may have accumulated to a point where it could take many, many minutes for CC to get past.

when did you last run CC?

how long have you left it 'stuck at 45%' before cancelling?
