My Desktop PC has developed a problem.  I first noticed it when I attempted to install TurboTax to do my taxes.  It wouldn't install and said it couldn't install because it was unable to install the current version of Visual C++ Runtime. It took me FOUR DAYS of checking all kinds of things to finally get it to install the current runtimes (x85 and x64), and TurboTax, including:

1.  Making sure Updates were current
2.  Attempting an install with Malwarebytes and Windows Defender turned off
3.  Running SFC /scannow
4.  Running DISM (Check/Scan/Restore Health) routines
5.  Restoring a backup (and then UPDATING EVERYTHING)
6.  Downloading the current Win11-64 ISO and installing it over the top of my current install, keeping my files/software
7.  Downloaded "MicrosoftProgram_Install_and_Uninstall.meta.diagcab" and uninstalls/reinstalls of the various versions of the Visual C++ Runtimes on my PC

I finally got TurboTax to install and do my taxes, but then I had to revisit the C++ runtimes all over again to be able to install Ashampoo Burning Studio 27 .... and to get an older version of software from Microsoft called "Snip" to work (I love that app).  Pretty sure this isn't the end of this gremlin and that it will bite me yet again with some other piece of software that needs to be updated.  Other than doing a "clean install" and having to give up some older purchased Adobe Software that does everything I need (Fireworks, that I can no longer "validate" since they don't do that anymore), is there something else I can look at to remedy this issue???  Have I overlooked something?
