1.5.0 Final issue with Windows 7 ESU and 8


i downloaded the new version 1.5.0 Cryptomator Windows and could not install it
on a Windows Professional 7 64 Bit (Latest Patch level including SP1 and Extended Support Updates April 2020). The same on a Windows 8.1 latest Patch level.

I always get the message
This program does not support the version of Windows your computer is running.

The old version 1.4.15 64 Bit runs still without any problems.

On https://cryptomator.org/de/downloads/ is written
Minimum: Windows 7 SP1
which i completely conform.

Is it a bug or do you not yet support Windows 7 SP1 ?

It would be sad because then I have to switch to an other solution.

this is a deliberate decision, since neither Windows 7 nor certain upstream dependencies are officially supported, which in turn makes it impossible for us to offer official support.

This is indeed our mistake. It should be Windows 10 Version 1703 (Creators Update).

That said, Cryptomator should run on older systems in theory. I’ll discuss if we can provide any unsupported installer. :slightly_smiling_face:

I’ll keep this thread updated!

An unsupportred installer would be great.

the 1.50 got a new kind of vault, means if I create a new vault with 1.50, the old windows 7 machine running the 1.4 version cannot work with it at this point, correct?

Yes. The vault formats are not downward compatible.

is there a chance to create with 1.50 a vault version wich is usable for 1.4?

Thanks for the fast answer. Do not worry about a rough and ready solution.
We had Cryptomator only on 10 clients for testing and will not loose any data.
Because of your honest answer, that you will only support Windows 10 we
habe renewed today our Boycryptor Licenses because they confirm they
will support Windows 8.1 and 7 ESU
(We will not migrate to Windows 10 because of privacy concerns).
Sadly Cryptomator was before 1.5 our prefered solution to move away
from Boxcryptor

There is a workaround for using Cryptomator 1.5 under Windows 7:

  1. you will need the installed files from V.1.5 (Windows 10; path=C:\Program Files\Cryptomator)
  2. copy it to a Windows 7 Computer overwriting the the installed files from Version 1.4.x.
  3. Start
  4. Use WEBDAV

Works for me - no bugs yet, as far as i can tell right now…
So, maybe the developers are kind enough to also release the binaries (zip Package).


Thx, i will try if it will work out!

Looks like it works also with not having webdav selected.

I had to update all vaults, so i was forced to try the windows 7 installation, thx for the hint!

glad i could help, for some reason dokan doesn’t work for me, don’t know why…

What issues With dokan do you have?

Cryptomator sais that the volumes were successfully mounted but when i try to connect via Windows Explorer an error screen pops up telling me that the volumes are not available…


very sad to hear, Win8.1 is not longer supported.
I also see it critically, that the new version of the containers are
not backwards compatible.

Is there a chance for the new version to support Win8.1?

I have no hardware which supports Win10.

Which Android Version is the newest which supports the old container?

Yes, as stated above, we’re discussing options for an “unofficial” version. In the meantime we have a GitHub issue available here:

webdav is working better for me as well, with docan sometimes de-mounting failed.

also, 1.51 was released already, it should support windows 7 and 8 / 8.1 as unsupported installer like overheadhunter mentioned

Maybe this might be solved by updating dokany to 1.30? Mine is more than 2 years old 1.20

I strongly recommend to update to the latest 1.3.1 as there were some major problems with the previous versions of dokany.

Our installer also contains now a routine to check the dokany version and notifies the user if it is outdated :slight_smile:

Interested too if there is a consensus about running cryptomator on Windows 7, even unofficial.

Reasons why I believe this is important:

  1. Long after XP was dropped support, many applications and companies still used it, because its stability and ease to secure it. Now, this is the case with W7, it is a very robust OS with better capacity of securing it (much less telemetry) and even if not officially supported by Microsoft anymore, it will still be used for long time ahead. So, I believe the rush in dropping apps support for W7 is premature and will backfire.

  2. W10 is a privacy nigthmare. Telemetry is difficult to block and it cannot be completely blocked. And crypto is a tool for people that love their privacy…so,you see how this two arguments blend in one.

  3. I personally will keep at least one of my machines running W7 for as long as possible, ideally until the machine dies of old age, so it would be nice to be able to use Cryptomator on it. Yes, this is a personal reason, but I am a person.


I hope there will be a reconsideration in regards to offering a compatible version for W7, even if no more support or assistance would be provided. Usually, workarounds found by users may or may not work on future updates, so I hope the dev team would consider releasing a W7 compatible version with each update.

Thank you for considering this issue.
