I have 5 versions of Ansys installed between 2 computers so I have only a 20% chance of starting the correct version and an 80% chance of starting the wrong version. If I start a version newer than 2020R1, then you won't be able to open the file after I save it. That wouldn't be ideal for you. Unfortunately, I don't have 2020R1, the oldest version I have is 2020R2 so you won't be able to open the file I save.
