slipstreamed 2003 install has problems

[DeaconCrusher]

Odd description I know, sorry. I used nlite to slipstream a copy of our corporate installation of 2003 with sp1 and latest hotfixes. Then customized the installer to do a stand alone install. It all looks great and works well (after a few tries <g>.) With one big and getting bigger caveat. Some installers crash with no info and doesn't even look like a crash, just disappears.

First time I noticed the problem was while trying to install adaptec storage manager. Some versions seemed to crash/shutdown/disappear right after through decompressing, other version ran and nearly completed but popped and incromprehensible error near the end (turned out this install was actually done and program worked.) Having similar problem now with Retrospect client installer, decompresses and disappears.

Saw a similar thing on another box using same install when trying to run nforce driver installers.

Anyone have any clue what I might have done while putting together the silent install?

Thanks
