Hi all, I have exactly the same problem when I push the MSI using SCCM. The first ngen.exe command fires at 5:02 PM, the last finishes at 5:41 PM! Now I've set the QUEUENGEN property to 1. The first ngen.exe command fires at 10:05:56 AM, the last finishes at 10:05:57 AM. Think I'm gonna leave the property on 1 Greetings
