To elaborate on a workaround for the standalone not starting up, here are the steps that may work for some (they've probably gotten to this point with you, though, already yorolpal:
- Go to your program files directory for T-RackS 5 and locate the T-RackS 5.exe file.
- Right-click on T-RackS 5.exe and select properties
- Select the compatibility tab and under settings, click "Run this program as administrator"
- Check the "Override high DPI scaling behavior"
- In the drop down menu, change "Application" to "System" or "System (Enhanced)"
- Click "Apply" and then "OK"
This should not affect other Windows applications so your scaling should otherwise remain the same. I know I can't go lower than 150% on this Surface Pro I'm on now or I'd go crazy and/or blind.
