Duplicati as a service in Windows 10


I have downloaded the 64-bit msi package (filename: duplicati- When I try to install Duplicati as a service in Windows 10 using the following command:
“Duplicati.WindowsService.exe install --webservice-interface=loopback --webservice-port=8200 --portable-mode”
I receive the following message:
“The program or feature … cannot start or run due to incompatibility with 64-bit versions of Windows. Please contact the software vendor to ask if a 64-bit Windows compatible version is available”.

Does anyone have a clue as to why? Makes little sense since I downloaded a 64-bit version of Duplicati for Windows.

Thank you.


Not seeing this in Duplicati forum or issues. Seeing some generic advice on the Internet, but maybe we can first try to narrow things down. For example, does Duplicati.WindowsService.exe help also fail, and how fast? What about any other Duplicati programs, such as Duplicati.CommandLine.exe help?


Hi, Duplicati.WindowsService.exe is entirely non compatible with my Windows 10 64-bit:

c:\Program Files\Duplicati 2>Duplicati.WindowsService.exe help
This version of c:\Program Files\Duplicati 2\Duplicati.WindowsService.exe is not compatible with the version of Windows you’re running. Check your computer’s system information and then contact the software publisher.

The Duplicati command line interface looks like it’s working:

c:\Program Files\Duplicati 2>Duplicati.CommandLine.exe help

See duplicati.commandline.exe help for more information.

Is this your initial Duplicati install? I’ve had some odd problems on my msi install unless the old version was uninstalled before the new install. Generally it’s been missing files, but maybe it could cause something like you’re seeing, however you’re apparently seeing a different message now. The one for “help” is sometimes interpreted to mean running a 64 bit program on a 32 bit OS, and the original seems to be saying that the opposite mismatch exists. I’m not an authority on this topic – just going by what I can dig up on the Internet.

If you haven’t already, please do an uninstall and reinstall from .msi. I assume that’s from www.duplicati.com and is intact. A right-click Properties on it should show a Digicert digital signature for Kenneth Skovhede.

Because Duplicati.CommandLine.exe runs OK (or at least better), let’s compare system-info. Mine starts:

C:\Program Files\Duplicati 2>Duplicati.CommandLine.exe system-info
Duplicati: Duplicati.CommandLine, Version=, Culture=neutral, PublicKeyToken=null (Duplicati.Library.Main, Version=, Culture=neutral, PublicKeyToken=null)

Update folder: C:\ProgramData\Duplicati\updates
Base install folder: C:\Program Files\Duplicati 2
Version name: "" (
Current Version folder C:\ProgramData\Duplicati\updates\

The ProgramData appearances are probably from my %DUPLICATI_HOME% but other info should be similar.

Sysinternals Process Explorer can show you the Image type (32-bit or 64-bit) of whatever processes are up, and Sysinternals Process Monitor can filter on Duplicati.WindowsService.exe to see how far it goes before the problem causes failure. Mine goes over 16,000 lines on a successful “help” command. Interpreting the output isn’t something I’m expert enough to do, but possibly you can see something going wrong leading to the fail…

This links to Dependency Walker and Dependencies. Possibly the (presumably) static analysis will give clues.

I’m stopping short of having you run a debugger, but if you’re into that kind of depth, it might show something.

Some of the Internet solutions for this involved uninstalling and reinstalling C++ components, but there was a report of other problems caused, which I probably can’t do much to fix. You can search and try as you see fit.

This ought to just work, AFAIK. I haven’t been able to get it on my system, and yours seems the first report… Sorry this isn’t going anywhere definite. It seems rather odd to me. Maybe someone else will have a thought.


I uninstalled and re-installed Duplicati and everything is fine now. I was able to install Duplicati as a service.

Thank you for your ideas and support.
