The Software and Cable you purchased from Radio Shack is not "ours", and has been on closeout (discontinued by RS) for several months. While it came with a CD, it doesn't support hardly any of their "current models".
Radio Shack sells a USB to Serial Port adaptor, however many of their people are not knowledgeable on things like this.
This is link to Radio Shack's USB to Serial cable:
The "USB to Serial" adaptor is quite common, and are available from Circuit City, Best Buy and even WalMart. They cost between $15.00 to $40.00.

Or you can find them cheaper at www.tigerdirect.com
WHATEVER YOU BUY - BE SURE IT HAS A DRIVER DISK INCLUDED.
We sell Scancat-Lite-Plus which retails for $29.95.
It supports all current Radio Shack scanners, but since the "Other Product" you have (Probably 20-048 SKU#) is not of our manufacture, we do not have an "upgrade".
I emailed Radio Shack the following and they referred me to you:
I have a Radio Shack Pro-89 Race Scanner with a serial cable and
scanner loader software. My new laptop has only USB connections. Is
there a USB cable available? Also is there a newer version of the
software available. My software was purchased about 4 years ago.
Do you have anything available?
