Environment
ZENworks Configuration Management 2017
Situation
After applying a dll or exe replacement for any ZENworks agent binary, error occurs on agent restart.
ERROR (in zmd-messages.log)
[Assembly.LoadFrom(C:\Program Files (x86)\Novell\ZENworks\bin\modules\filename.dll) threw exception during module loading
Type: System.IO.FileLoadException
Message: Could not load file or assembly 'file:///C:\Program Files (x86)\Novell\ZENworks\bin\modules\filename.dll' or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515)
Resolution
Unblock the exe or dll by right click / properties / security / Unblock. Restart the ZENworks Agent Service.
Cause
The problem is unrelated to the actual patch. Windows may block any dll or exe when copied remotely via a share. This won't happen using bundle method to install the FTF.
