If anyone else stumbles upon this, here is a
Workaround for removing the old installation entry:
- Backup your app settings by making a copy of
%appdata%/Cryptomator(e.g. temporarily store it on your desktop) - Uninstall all Cryptomator entries from Programs and Features
- Reinstall the latest Cryptomator version
- Restore your
%appdata%/Cryptomatordirectory
Beginning with Cryptomator 1.4.15, all newer versions will use the same installation IDs and therefore you will only see one entry.
