I lost or didn't get an app CD with a refurbished 70D I bought from Canon. I emailed Support and responded with steps to obtain the programs::
"Thank you for your inquiry regarding your EOS 70D. I will be glad to assist you in downloading the software from our website.
Let's start by going to www.canoneos.com.
On the new page that loads, click on DRIVERS & DOWNLOADS lin on the top right. Ener your camera model in the prompt under step 2, select it from the options that load under the box, and then press the GO button.
You'll also want to change the operating system from Windows 10 to Windows 8.1. That version should be compatible with Windows 10. It's just how our site is set up for some of the larger files.
When the camera page loads, click on the SOFTWARE heading. At this point you'll see an option for the EOS Digital Solution Disk Software. You will need to load this version before trying to get any of the specific updates on the site.
Click the DOWNLOAD button. You'll then be prompted to add the serial number, which you can find on the bottom of the camera or on the warranty card listed as the Body Number.
Then save the file to a convenient location on your computer.
The file you download is actually a zipped file. When it finishes downloading, you'll want to right click it and select the EXTRACT option. This will create another folder by the zipped file with the same name. Open the folder and double click the file, and that should start the installer.
Once you've loaded the software, you'll want to use EOS Utility to download from the camera. Look for it in you PROGRAMS list, inside the CANON UTILITIES folder.
Please let us know if we can be of any further assistance.
Thank you for choosing Canon."
