This potential fix is not exactly the same issue you are having however, I'm not coming up with any other ideas at the moment. 

Lacerte program or a Lacerte pop-up window opens off screen

→→ Option 2 - Troubleshooting manually

Close the program

Press the Windows + R keys to open the Run command

Type %appdata% in the Search (Run) field

Press Enter, then open the Lacerte folder on the new window that pops up.

Rename the configuration (ini) file for that year (e.g., W16tax.ini for 2016 Lacerte).

Re-open the program
