Unable to mount Filesystem (Win 10)

The error “Cannot install driver”…

… indicates that Dokany is not correctly installed. If you look into your log files, they contain the lines

[App Background Thread 003] INFO  com.dokany.java.DokanyDriver - Dokany version: XXX
[App Background Thread 003] INFO  com.dokany.java.DokanyDriver - Dokany driver version: XXX

The X’s should be replaced by some numbers. If the Dokany version is not followed by a meaningful number, it is another evidence that it is not installed properly.

As a workaround…

… you can switch to WebDAV in the general settings, but it has drawbacks (e.g. the file size is limited to 4GB).

To fix it…

…you can try the following procedure (and when I say reboot, I mean a reboot and not turning it off and on again :wink: ):

  1. Check, that the files C:\Windows\System32\dokan1.dll and C:\Windows\System32\drivers\dokan1.sys exist.
  2. Uninstall Dokany over the Apps & Features panel
  3. Reboot
  4. Check, that both files do not exist anymore
  5. Install Dokany (I recommend the currently most recent one)
  6. Reboot
  7. Check that both files are again present

Afterwards Cryptomator should run fine.

Edit: Updated to also look for the system driver
