First of all, you can get a Windows 7 ISO image of the version you need in 32-bit.
You should have ordered your laptop with Windows 7 Professional then you could have run the 32-bit Windows 7 in virtual machine mode.
Don't berate Windows 7, it is an excellent operating system, you're just not familiar or used to it yet... give it time.
Maybe it's time to rewrite the programs for 64-bit hardware since that really is the standard now.
I realize that reinstalling is a P.I.T.A. but if you really want to run your 32-bit software you'll have to have an X86-based operating system.
