Today i updated from 1.4.9 to 1.4.11. Since the update, my decrypted disk crashes and afterwards i need to mount the disk again. After a while it crashes again. On 1.4.9 everything worked.

Seems to be related to #888. Didn't see this stack trace in that issue, so maybe it helps.

Upgrading Dokany from 1.2.0.1000 to 1.2.2.1000 resolved the problem. Is it maybe better to update Dokany too when updating Cryptomator?

Thank you for your bug report! Dokany as a dependency is making everything so tricky. We're following the instructions/suggestions from here: https://github.com/dokan-dev/dokany/wiki/How-to-package-your-application-with-Dokan

The Dokan driver can not be installed as an upgrade becausee it requires an intermittent reboot for the uninstall of an existing version.

This is probably the saddest thing ever because we can't give Cryptomator users a convenient way to update Dokany once it's installed on their system.

BUT since it is possible that Dokan library will be updated by another Dokan application, the update might break link dependency to your application. Therefore it is highly recommended embedding the dokan1.dll in your application folder. Doing this will retain compatibility of your application with all MAJOR versions equal to the library you embed.

We actually updated the dokan1.dll file recently and maybe this caused the problem... but... why? Shouldn't dokan1.dll work with any installed Dokany driver with major version 1?

@Liryna Any ideas on this one? Maybe we were just unlucky with the latest version of dokan1.dll (version 1.2.2.1000)?

Just got the same report here https://groups.google.com/forum/#!topic/dokan/d-47ztI78Y8

In the newest library we are using a new keepalive mechanism that prevents to have zombies drive in case the user fs crash. Currently an older library work with the newest kernel driver. Here the keepalive fail to establish since kernel does not have the feature in the install version. We maybe had to have a fallback to older keepalive mechanism 😢 will look to add it for next release. I can understand updating the driver (rebooting) is not the best UX but there is not much we can do for now dokan-dev/dokany#669

Thank you for the info, @Liryna! All right, we'll repackage our installer with an older version of Dokany in the meantime.

New installer is available at: https://dl.bintray.com/cryptomator/cryptomator/1.4.11/Cryptomator-1.4.11%2B114-x64.exe

At least one confirmation that it works: https://community.cryptomator.org/t/version-1-4-11-fails-after-a-few-moments/3748/5

Fix is ready and will be ship next release 👍
