I also have this problem. Running windows 10. I have been in contact with support, who told me to uninstall the game, then re-start the PC.Then delete the folder Topgolf here: C:\Program Files (x86)\Topgolf
Then to re-start the PC again and install the app from wgt.com I even re-started my PC after the game had downloaded new files, before getting the PLAY option. After doing all this, the game still do not launch.When clicking PLAY, a small box comes up with a progress bar in the bottom. After 2-3 sec. the box dissapears, and nothing more is happening.
