Hi Thomas
Sorry for the radio silence here, things have been busy but I have been working on this and actually published some changes yesterday.
So, in the first case, as we've discussed already the scenario is not currently supported by the installer. It is possible to install, and then customize the environment afterwards and get things working as you've seen. Important to note that with the current 2026.3.0 release and earlier, the installer does not understand custom service accounts. So if you do a repair or reinstall, some or all of the customization will need to be reapplied afterwards.
Next, the next version(s) of Gateway will support your use case out of the box. It's not quite complete: for the initial install, you'll need to run the MSI manually (not via the DVLS console) and specify the service account as a command-line argument. After that point, if you're using a passwordless account, upgrades or repairs should be seamless. Importantly, if you install now and customize, the upgrade should recognize your custom account and things should continue as normal. There are some edge cases if you're using an account that requires a password, but that does not apply in your case.
Finally, I've drafted some documentation around all of this (the current state with manual customization and the upcoming improvements). Currently that lives on GitHub (Devolutions Gateway is an open-source project).
I'd encourage you to take a look, try this out and give me any feedback. You'll probably be the first person that I know doing this.
In terms of taking this forward, we'll work on baking this feature into the DVLS Console and migrating the documentation to the official Devolutions documentation portal. That will likely take a bit of time, and like I said your feedback will be important as we may need to make further refinements.
Please, let me know if something isn't clear or you have further questions
Kind regards,
