Troblem with the registry clean

A few days ago... I have a probelm with the registry cleaning

it stuck at 3%

My version: 3.7, and 3.8

I am using win 7 64bit

first, 3.7 is very old 3.28 is the latest. Second read my signature. Third probably your antivirus is stopping registry changes, what product do you use?

fourth, welcome. we can definitely help you
