Backup an installed program to put on new OS? Have key, lost CD cant find software anywhere online

[SleepyAl]

I have an old Sony VAIO laptop that my dad and I shared when I was younger. It's a 32 bit OS and since some newer games require 64-bit OS I was going to format the laptop and use a Windows 7 key I bought long ago to then get Windows 10.

The problem is there's one specific program on the laptop my father still needs, but he doesn't have the CD for it anymore. I found the CD Key via Registry but a fat load of good that's gonna do if I can't get an installer or CD for it. Looking online on various websites I cannot find the software anywhere, not even on the developer's site (they don't sell it anymore) or on any shady sites. It's called VersaCheck 2004 Silver Express, it's for printing checks and he needs it for some specific reason I can't remember off the top of my head.

So, since I can't find this thing anywhere, my only recourse is to somehow backup the program and then plop it onto the new OS. I know a simple copy/paste is not gonna work because of registry keys and .dlls and such but I have no clue how I'm supposed to accomplish this and copy every single hidden bit of the software embedded in the laptop. Googling software gives me some products that have "optional 3rd party software" adware in them that I don't quite trust. Is there some way I can do this manually, is there some freeware or paid software that would do it that isn't ridiculously expensive? Any help would be appreciated but I'm not expecting miracles.

If you have installed 32-bit os from manufacturer,your laptop may be not support the 64-bit os

Long story but originally the laptop came with Win 7 x64 but I had to get a new hard drive cause it died, and the Windows Product key sticker wasn't on the laptop anywhere so I used a 32-bit key I had from my desktop when I upgraded. Later on I bought a 64-bit Win 7 key cheap with a student discount but never got around to using it. So I know for a fact the 64 bit OS will work on it.

Have a look through C:\Windows\Installer - there may be a cached MSI installer. You might get lucky, the MSI sometimes contains everything needed to reinstall the package. Other times, you will need the original data.cab / setup.exe too.

"32-bit" keys should work fine in 64-bit versions of Windows.
