I'm sorry this is so very off-topic, but I've tried Google and can't figure a search that will get me the info I need.
My problem. I've been migrating my apps to a new PC, and I find a couple of my original distribution disks have gone missing.
One of them is my ProPack upgrade for Poser 4 disk.  I'm not looking to get a copy of the disk, I have it installed on my older computer, but I'm planning on scrubbing the hard drive to donate it to an indian reservation school.  I do have have the manuals and serial numbers (I actually bought two copies of ProPack so I could use one on a friend's computer, but he passed away and I scubbed his disks long ago so his widow could sell his laptop), but my actual disk or disks aren't with my other Poser disks ( I have install disks for all the versions except for Version 2 - it was on old floppies and don't have a drive to read them in anyway). 
I once had a program that would un-install an application into a self-installing exe to aid in migrating to new pc's, but that was years ago and I wouldn't trust it to use on a more modern app. 
I've looked at several programs like PC-Mover and PC-Relocator and such, but they're all designed to move whole systems and settings, not individual apps.  Last time I used one and found tons of obsolete crap in my drivers and settings so I'm resistant to use one again; I've already fresh-installed most of my aps anyway, I just have a couple of odds and ends that I can't find the original downloads or distribution files (NOT warez or cracked software - I don't use them).

Anyone know of any such programs?

This is/are a program/programs I've purchased and used for some time - I just need to get it/them over to my shiny new computer.
