Unable to get licensed Duplicacy Instance (with configuration) on Windows Startup (Install as a service)

Support
#1

Been using Duplicacy for a while and have a personal WebGUI license. Usually I start it up manually, but I have been trying to get it to start automatically on Windows startup. Following the guide here: Duplicacy User Guide I reference the following location for my service: C:\Users<username>\AppData\Local\Programs\DuplicacyWebEdition\duplicacy_web_win_x64_1.7.2.exe. However, when attempting to get Duplicacy to start up automatically, this just results in an unlicensed version of Duplicacy starting up in the background missing all of my configuration. However, if I shut down the process and use my Start Menu link (which appears to reference the exact same file), my licensed version of Duplicacy seems to start up with all my configuration there.

Logs show the following after a start up.
2025/07/02 07:42:25 Failed to contact the license server : Post “https://duplicacy.com/request_license”: dial tcp: lookup duplicacy.com: no such host, reference

I’ve take a look at some other posts, but can’t seem to find an entry that matches my particular problem. I’m not sure if the issue is related to the fact that it can’t find my license, can’t validate it on start up, or possibly something else? Thanks in advance for your help.

This is a dns issue.

How are you trying to accomplish this? Running as a service? You may try to change the user from system to your user, or perhaps check if the service is allowed to communicate with the internet.

I’m not very familiar in how windows works, but answering your question, the root cause form your log is that duplicacy cannot resolve the host.

Thanks for the reply.

Based on what I’ve read here: Duplicacy User Guide I should be able to install this as a service via the following entry so I don’t have to start Duplicacy manually every time my computer restarts:

Or you can run this command in an administrator DOS prompt after the program has been installed:

        \path\to\duplicacy_web_win_x64_1.1.0.exe -install-service

A new service, named Duplicacy Web Edition, will be installed and started automatically. You can then open the web browser at 127.0.0.1:3875.

I set up the same version of the executable that my Start Menu short cut references. Not sure if that was correct or incorrect? Might there be a better way to go about accomplishing something like this?

If you run the windows installer for duplicacy web version with elevated privileges there shall be an option to install as a system service.

In this case it will keep data under ProgramData as opposed to your user home folder, and configure windows service manager to start itself

But we still need to figure out why does it fail to connect to your dns server.

You’ll need to move your configuration:
