Deleted entries return after registry cleaning

[seventhson]

After I did a scan with registry cleaner and deleted entries they return. They are application path issues from downloaded install exe files I've deleted. After deleting those and a couple of other entries and then closing CCleaner,  they return on the next scan. Why is this happening and what should I do?

ver 4.11.4619 and I am going to update. It is on a Gateway netbook with Windows 7 Starter

They reappear cos they may be necessary. Easy to resolve. Right-click the items and add to Exclude list.

Ok, but I don't see how a deleted installation file is necessary, if it's deleted it's gone. But they haven't returned yet after updating to ver 4.12

I had the same problem until I temp disabled my AV until After Restart (Before running CC, and I always do a no-activity restart/ wait 15min for All files to release)!
