3 choices ...
1. If you have or can purchase a licensed copy of Windows XP you might try the
Oracle's VirtualBox to run a Virtual 32-bit XP environment under W7x64. And then try running the older software in the virtual environment.
2. You can download the 32-bit Home Premium
Here. Use a download manager to download the file (as it is huge and you will want to be able to resume if connection is lost) and then burn it to a DVD (can be done with a product like
IMGBurn). Note: the 32-bit version may be available from the manufacturer, most likely for a fee, but it would have the advantage of including any of their custom software, so it may be worth a call to ask.
You will probably also be asked to enter your existing Windows 7 product key; download and install
SIW then when you run it go to the Software .... Licenses section and write down the keys there.
It is recommended to go to the computer manufacturer's site, as well as the websites of your other components (video card, sound, network, etc) and download the 32-bit drivers so you have them and burn these to a CD. Most of these will be found automatically when you install W7x86 (32bit) but they aren't always the latest and most importantly you will have any that W7 can't find. You should also gather all your program discs as you will need to reinstall those after you reinstall the OS. Then back-up your data. And finally boot from the 32bit W7 DVD and install everything.
3. You may be able to buy more current Windows 7 compatible software to replace those 2 programs.
