Install via software center works, but fails after 1st MSI in OSD TS

Here is puzzle for you guys.

I have PSADT setup to install three msi files. It works perfectly via powershell, and it works just as well via Software Center (running as system).

I have the same package configured to run during an OSD TS and it will install the 1st MSI but always fails on the second MSI.

Any suggestions?

Did you check out the PSDAT logs to see why it’s failing?
