Hi team,
Noel - I tried adding BIAB to the ESET exclusion list. No dice. I get the same error. I'm really beginning to think this is a registry error. I use some good quality third party software, such as Photofiltre, Color Cop, and Notepad++ . Some third party software has proven to be garbage, so I uninstall it. The ESET program is also very good at flagging suspicious .exe files. I immediately let ESET delete them. Even at that, perhaps my registry has become corrupted.
So, I think there are two choices left: a reinstall of Windows 7 or upgrade to Windows 10. Would someone please roll the dice for me? And please, don't worry about over-beating me with solutions

. I really want to get to the bottom of this. Your suggestions are very much appreciated. I consider myself lucky to have all of you chiming in. I only hope I can return the favor someday! Thanks.
- Lee
