Windows 7: .NET errors while using "Dual Monitor TaskBar" - FIXED

13 May 2017   #1

Windows 7 Ultimate x64
.NET errors while using "Dual Monitor TaskBar" - FIXED

I'm posting this problem and solution for the purpose of helping others who may encounter it.

As you are well aware, Win7 has some features missing that have been present in many Linux distros for a long time and have only been implemented in MS OSes since.
I have small programs to add these.
One missing feature is having a TaskBar on each screen of a multi-monitor setup.
While there are a few comprehensive commercial solutions for this, there is a basic free one for two screens, named Dual Monitor TaskBar.

After a recent slew of WU .NET updates and .NET security updates I began to get related error dialogues pop up under some circumstances (not pinned down) where I had Explorer windows open on the same screen as the additional TaskBar.
The result would be that the open window boxes on the additional TaskBar would blank out and the content would be replaced by red Xs spanning the entire boxes.

MS provides a small .NET fixer program which, to be fair, seemed to do a good job of scanning and attempting to repair .NET versions, if not being able to fix the problem.
At least it ended with advising me to possibly reinstall .NET 4.6.1

Well, I didn't get that far but, due to information in one web discussion tab I had open relating to .NET issues with a different program, there was suggestion to download the .NET Framework 4.6.2 offline installer, which I did, subsequently ran and have had no more issues so far.

As it's likely many folk have used this small free program to add omitted features to Win7, I'm guessing this may occur for a few users.
Hence, I'm posting my findings for others' benefit.
