Error opening Cryptomator after latest update

I had Cryptomato installed and god a notification (Windows 10) of update available. I did download/update now just opening the program I get the following:

Can you do the following and provide a full log file afterwards?

  1. (Re-)Start Cryptomator
  2. Enable Debug Mode
  3. Attempt to unlock the vault
  4. Quit Cryptomator

Debug Mode can be enabled in the general preferences, you also find there a link to the log file location. The log in question is named cryptomator0.log.

As i thought, Dokany is not properly installed your system, there exists no driver with version “0”. (it should be 400)

You can either try to uninstall and then install it again or you can switch to WinFSP, see WinFSP: How to use it.

I have this issue periodically and on multiple windows computers after the latest update.
I’ve re-run the WinFSP.msi and went for repair… it doesn’t seem to help. I have to be fair… I’m not fond of external packages in general, I’m wondering if I should switch to WebDAV instead?

\EDIT: Not even WebDAV works…This below is a newly created Vault after switching the settings to WebDAV. Why did this use to work in the prev version but not on the latest?

This message indicates a system configuration error. Search our forums and the internet for “System error 53 The network path was not found”.

Related articles are for example:

To understand the problematic a little better: With selecting WebDAV Cryptomator is starting a local-only server, which is used to operate on an unlocked vault. The unlocked vault is integrated into the Windows Explorer with the net use command.

A VPN, a proxy server or security software can inhibit this on different ways (e.g. blocking access to localhost). A good overview from Windows is System Error 53 Has Occurred. The network path was not found. - Microsoft Community.


Using WebDAV has some drawbacks, for example it is slow in general and the file size is restricted to 4GB in Windows (4 GiB file size limit on virtual drive)
