Hi, DarrylCox!
You can download the EOS Digital Solution Software by going HERE and then select Windows 7 (regardless which version of Windows you're using), and then select "EOS Digital Solution Disk Software 29.1A for Windows (For users who cannot use the bundled CD)". When you select that, you'll be prompted to enter your serial number. That's the DIGITS from the bottom of your camera near the tripod mount hole. The software download isn't picky about your product, it just needs to be a Canon Camera product. It looks like this:
After you've gotten that, you'll want to update your software to the most current version for Windows 10 by going to the Windows 10 (64-bit) dropdown and select the most current versions of the software you'd like to update (most likely just EOS Utility & Digital Photo Professional).
If you get stuck, don't hesitate to reach out to support. They're at 1-800-OK-CANON (800-652-2666) weekdays from 9am to 9pm (ET) & Saturdays from 9am to 7pm (ET). Support at Canon USA is right here in the USA.
If you're outside of the USA, you'll want to reach out to support in your country HERE.
