Can't install Review Heatmap

When I click the Get Add-ons button and paste the code (1771074083) into the code box, then click OK, I get a small yellow box saying “No updates available”. I have restarted Anki and reboot my system several times but the result is the same. I am on Windows 10 using Anki Version 2.1.56. I do not have an earlier version of Heatmap installed. The only add-on I have installed is Migaku Kanji GOD, which seems to be working fine. Any help you could give would be appreciated. Thank you.

Thank you. I was able to install Heatmap by first disabling Migaku. Once installed, I enabled Migaku and everything seems to be working now.
