I have downloaded the 2020 tax program (apple Computer with parallels and Windows 10). When I open the programm I get the normal screen but nowhere to enter my E-Mail and Password to run the program. I have tried changing the appsettings as someone had suggested and also disabled High DPI Scaling Override. I have uninstalled the program and reinstalled. The same problem continues. I really don`t know what to do next and need to start using the program soon.

Has anyone else had similar problems or can suggest any useful tips?

P.S. I am in Germany - I don`t know if that has any influence on the combination of programs used!!
