Since beta 18, I’ve been having the same issues with installing the update. Despite uninstalling previous iterations of Scrivener (including V1 – I’m just using the beta right now), the same things happen:
- Double click installer. Nothing happens.
- Try to run as admin. Nothing happens.
- Run compatibility mode.
It’ll work if I run it in compatibility mode for Windows 8. Same for the uninstaller – it needs to be run in compatibility mode for Windows 8. I’m running a 64-bit Windows 10 machine.
