I found this on another iFixIT site. Maybe it will be helpful.

The old version of Connect for Leaptop is available from the Internet Archive. It took me several tries to download but once I got it installed it worked and all the audio files (for names, etc.) are still available (at the moment) on Leapfrog’s servers.
The original url was: http://lfcdownload.leapfrog.com/en/pc/my...
The archive.org version is https://web.archive.org/web/20170615142439/http://lfcdownload.leapfrog.com/en/pc/myownleaptop/LeapFrogConnectOfflineSetup_MyOwnLeaptop.exe
I had to DISABLE my internet connection when starting the program - otherwise it wants to (really, forces you to) “upgrade” connect and the new version doesn’t support the Leaptop. Then, I had to re-enable the internet to get the software to work once it was running.
