I was testing the writing software Scrivener (for Windows), and ran into an issue. The installer would just freeze up completely on start. It would run, eat CPU time, and show up in the task list, but ultimately never showed any GUI.
Once it randomly worked, the application Scrivener itself had the same problem.
I then tried the Scrivener 3.0 Beta and it had the exact same issue.
Thanks to assistance from Scrivener’s support team, I was able to identify the cause: I had Wacom drivers dating from 2017 installed, as they were the latest for an old tablet I own. Uninstalling them solved the issue. The drivers for my current Wacom tablet do not interfere with Scrivener.
Hopefully, the Scrivener developers will fix this at some point, but until then: If you try to install or run Scrivener and it doesn’t work at all, make sure you do not have old Wacom drivers installed.
