We are sorry to hear that you are running into some troubles with getting the trainer to work in Anki. Here are the most common issues (and their solutions) that we see.
Do You Have the Right Program?
The very most important thing to consider is if you downloaded Anki from the original site. There are a lot of similar programs out there, but our materials work only with the original version. You can find that program here: https://apps.ankiweb.net
Are You Trying to Install While on a Mobile?
While our products do work on mobile devices, it's best to first download them to a computer and then sync that with your mobile device. Downloading directly to a mobile device doesn't always work as well.
