Hey papabear, do you see this golf folder...
...at this location in Windows explorer?
C: \ Program Files (x86) \ Topgolf \ WGTLauncher
If it isn't there, then try running the installer again (WGTLauncher.msi in your downloads folder). Don't uninstall the game, just reinstall again. If any files/folders are missing, hopefully the installer will add those. Then try running the game again.
