Installed and have been using TTax 2022 for the past month.... receiving updates as we go...

This weekend - Feb 18, 2023 - tried to perform the internal update and it failed... Windows 1603 -

Tried a few things, none worked - so just don't click on the "check for updates" anymore.

SO... WHAT HAPPENED ??

Noticed the "help" comments mentioning .NET issues....

So, it appeared that Windows Update installed a .NET update last week - Feb 14 -

and today is Feb 18, 2023 - wondering if the Windows update broke something inside TTax ?

Lastly - I am replying to this existing 1603 topic -

since I could not see how to create a NEW topic on the forum ????
