I am having problems with the upgrade to 1.6.8, however, only if I use the .exe installer. If I use the .msi installer everything works fine.
I have been using the .msi installer for previous installations and installed the WinFsp package manually. Noticing that the .exe installer comes with the latest version of the WinFsp package, I decided to switch to the .exe installer, hoping not having to worry about the latest version of WinFsp in the furure.
The .exe installer however, still seems to stumble across a “Running instance of Cryptomator”.
Several tries to uninstall Cryptomator and WinFsp, rebooting after each action, did not solve the issue, neither did using ProcExplorer to spot the running instance.
A workaround (for me) is to keep using the .msi installer and manually install WinFsp. It would be nice however, if this somehow could be fixed.
