Missing CoCoL.dll

Installation

Hi,
I had problem after upgrade Duplicati from 2.0.4.5 to 2.0.4.22_canary. After instalation MSI package on Windows 2016 Server is missing CoCoL.dll.

System.Reflection.TargetInvocationException: Cíl vyvolání způsobil výjimku. —> System.IO.FileNotFoundException: Nelze načíst soubor nebo sestavení CoCoL, Version=1.5.0.24305, Culture=neutral, PublicKeyToken=0983de3c914beeaa nebo jeden z jejich závislých prvků. Systém nemůže nalézt uvedený soubor.

v Duplicati.Library.AutoUpdater.UpdaterManager.RunMethod(MethodInfo method, String args)

Instalation on Windows 10 is OK. I copied file CoCoL.dll from Windows 10 to Windows 2016 Server and I restarted Duplicati service and everything is OK now.

I have seen reports of this before. I suspect that it is antivirus or similar that removes the files after installation. I have not seen any confirmations of this though.

OK, I’ll try to check it out.

I’ve had random Duplicati files go missing after installing from .msi without uninstalling the old version first.
