Hi,
We had the same problem. You'll find it should work on the PC with the full client installation of AdminStudio but not your repackaging machine with only Repackager installed (either standalone or remote.)
Create the following key on the repackaging machine/s with the problem machine and it should fix it. (if you already have this key, and have a value set then you have a different issue.)
Path: HKEY_LOCAL_MACHINE\SOFTWARE\InstallShield\16.0\Professional
Name: ProductSKU
Type: REG_SZ
Value:(get the value from the machine with the full AdminStudio install)
I raised this via Support on Jan 26th, but despite a number of 9.5 Service Packs that have come since its still not fixed.
Work order for the bug is: IOA-000053130.
Cheers,
Craig
