Level Viewer setup doesn't work.
Unity installation works, but OpenCAGE fails after for unknown reasons. I already have Unity installed, and the latest level viewer is present (and in fact, works if i use that unity installation).
does it give you any error messages? what represents a 'fail' here, what actually went wrong?
The error message is "Level Viewer setup failed! [new line] Please try again." The message on the progress bar is "Installer failed!" and is full.
you can reach this state if the unity installer itself fails or exits early - did you complete the unity install first, and were there any warnings/error in that installer?
No. The Unity install completes successfully with no issues. The needed version of Unity is already installed however (because I used the Level Viewer prior to the auto Unity install), but the installer successfully reinstalls Unity.
