Ed,
Thank you for your post.
I tried the suggested solution of modifying the file name. Unfortunately it did not work for me either.
My continued research about tax software I discovered that some of the competitor tax filing programs operate with .Net Framework 3.5. Even though I found nothing specific about Turbo Tax pertaining to .Net Framework 3.5, I wondered if the TT worked the same way. So I went into my settings/control panel (depending on which version one is running), "apps"(programs), "optional features"(turn on windows features), and then "additional windows features" (left clicking each time) until a list appears that contains .Net Framework options. Left click box to add .Net Framework 3.5. One can leave the .Net Framework 4.8 boxed checked as is.
Windows will then search, download and install .Net Framework 3.5. Hopefully that installs without any problems.
In my case, the installation failed with error code: 0x800F0922. This error code was dealt with by going to Microsoft's website using the link
After completing this download and installation, I returned to my settings/control panel, and repeated the steps for adding .Net Framework 3.5 with success.
The impact on the TT program was I was now able to open it without any further Access Violation errors and the program was operational.
My guess is that while a known competitor to TT visibly asks to add .Net Framework 3.5 as part installation, I suspect TT does it behind the scenes. However if your computer has an underlying corrupt file pertaining to it such leads to the encountered issues.
I hope this post is helpful to all that encounter the same difficulty. For those who are interested, Net 6.0 is available from Microsoft
Stay Well and Stay Safe
