A customer said "I just installed Windows 11 and my 941 Form is not filling in the form." If you were a PayWindow user when Windows 10 was released you may may recall we had this same problem when Windows 10 came out and they took the file association away from Acrobat and gave it to Microsoft Edge. Now Windows 11 is doing the same thing.

The same solution applies here, PayWindow uses Adobe Acrobat so see the instructions in this PDF:
