Can you tell us what keyboard you are installing? Is it one from our site? If so, please tell us which one. If it’s one distributed from elsewhere, we may need you to upload it somewhere (like Google drive or dropbox) and send us the link.

Also, are you using a Windows computer, macOS, Android phone or something else? Which version of Keyman are you attempting to install?
