What error message did you get? Could you post it verbatim?

First thing to try is read this article:

https://proconnect.intuit.com/community/help-articles/help/repair-or-reinstall-microsoft-net-framewo...

the Error Message:

ProSeries has detected an issue with a Microsoft . NET Framework file that will prevent ProSeries from running properly. Please follow the instructions in the link below to correct the issue. If the problem persists, restart Pro Series.

The link points to Intuit home page ... 

 I tried the steps still receiving the error

Yes, everything is up to date...

Please try renaming the user.config file. 

1. Locate your Intuit,_Inc file by going to  C:\Users\username\AppData\Local\Intuit,_Inc

    "username" should be your username for your computer.

2. Locate the correct folder in here. It should be named Protax21.exe_ with random symbols at the end.     You may have 2 of them, one for Basic and one for Core. 

3. In each of the above folders locate the 0.0.0.0 folder. Change or delete the user.config file
