2.0.2.15 won't start

Support

I upgraded one of my machines from 2.0.2.1 to 2.0.2.15. (Windows 10 x64)
After upgrading the TrayIcon process won’t start.

The following events are visible in the Event Viewer.

How can I troubleshoot this further?

Application: Duplicati.GUI.TrayIcon.exe
Framework Version: v4.0.30319
Description: The process was terminated due to an unhandled exception.

Found a bit more detail in Duplicati-crashlog.txt:

Ok the CoCoL.dll file was not present in the Duplicati 2 program folder. I got a clue from this thread:

I uninstalled 2.0.2.15 and then reinstalled it clean. Now the CoCoL.dll file is there and it starts properly.
The in-place upgrade over 2.0.2.1 to 2.0.2.15 failed to install the dll.

You guys might need to look into the installer logic a bit more.

Thanks!

Thanks for bringing this up - and glad you figured it out!

It is a known issue and there was a change made to how updates are handled somewhere in the 2.0.2.1x range (I think). That change should make issues like yours happen much less frequently - but only once you’re on the new code for both the “from” and “to” versions of the upgrade.

Please let us know if you run into it again now that your on the new update code.

Oh, and sorry for the delay in replying - sometimes life intrudes on my internet time. :anguished:

Thanks for the reply! I think it would be beneficial to try and change the installer logic to make sure that DLL gets installed properly, even if someone is upgrading from 2.0.2.1. Seems like this may be a common scenario since many won’t be using canary/experimental builds.
