InFinRetirement: Hmmm! I'm also a little puzzled about what you want to do, but must disagree with TBone - There IS a way of copying programmes from one disk to another.
It's a programme called Norton Uninstall (disclaimer - I don't work for Norton of Symantec). Norton Uninstall (as the name suggests) allows you to remove a programme from your machine (mostly fairly successfully, but not always). It also allows you to "Store" a programme (the programme "appears" to be still installed, but if you try and run it, Norton Uninstall pops up to point out that it has been stored and offers to re-install it - good if you haven't got too much disk real estate left. You can also "copy" a programme to another disk (or another machine).
I recently had a problem with my SCSI hard disk (prognosis was "massive software conflict"). Solution was to install another hard disk (as the bootable C: drive) and relegate the SCSI disk to being the D: drive.
Windows was completely re-installed on the new C: drive (which sorted out the "massive software conflict" by creating a new registry).
I then used Norton Uninstall to "copy" some of my programmes across from the old drive to the new drive. You point Norton Uninstall at the programme you want to copy, and it bundles it all up (including the data files) into a self executing file. When you execute this file, it asks you where you want it to go, and hey presto! that's where it goes. Note well that it copies the data files too - I used it to copy Symantec Act! (which is a contact management system) and it copied and re-installed the entire contact database. This is very much easier than re-installing the package off the original disk, and then battling to set all the fiddly options before installing the contact data base (which is actually a number of files that go into different directories).
So Norton Uninstall comes highly recommended (and it's not very expensive - about 50 quid).
However, it didn't manage to copy Microsoft Word - that had to be completely re-installed because the "copied" version bleated about some missing files. So you might need to mess around a bit (and at least you won't need any viagra for this kind of messing around)(joke!)
The other thing you might luck out on is that some packages install complete with their set-up files. These you could copy (use the right mouse button and "copy" rather than "move") the entire programe directory from the old disk to the new disk. Then, from windoze explorer, click on the "setup" icon and it should re-install on your new disk.
That assumes you are re-installing a new copy of your operating system onto the new (?) disk ...
One thing I certainly do NOT recommend is messing around trying to edit the registry. That is an area where angels should fear to tread. I know, been there, read the book etc etc and it took me three weeks to get the system back to where I wanted it.
Good Luck! (You may need it!)
