I've created an installer which contains an exe and 24 installer files. Each file is 250MB except for 024 which is ~231MB. installer.exe-installer.015 are on disk one, while installer.016-isntaller.024 live on disk two.

At the same point every time during the install (disk two) the program will 'freeze' taking ~50% CPU and never comes back.

* Several files on disk two install properly
* File which eventually freezes begins to decompress
* Individual file progress bar stalls at ~80%
* ~30 seconds later individual file progress bar jumps to 100%
* The 'X' on the title bar becomes disabled
* CPU usage for installer is listed at ~50%
* Installer still responds to being dragged and minimized
* Cannot continue on from here and have to end the process

This same installer runs correctly from a local folder as well as from a network share. Tested DVD version on machines with and without anti-virus to see if that might be the problem with no luck.
