Using Zenworks Trying to make an app that does a quiet install of a third party product called Onbase Office add in. It comes in an EXE file with 2 MSI's inside it, one is the program and the other is a pre requisite that has to install first. DM Runtime 8.0 DST. So naturally I made an app to do the pre req seperately. I used the MSI installer files that are left in the Windows\Installer folder after a successfull install. Obviously running the MSI manually works fine, but when trying to do an automated install with zenworks it fails. The windows event log says that the product could not locate cabinet in stream: Why would this happen when doing the install with zenworks?
