Retrieve license key for Ver 1

A few years back, I purchased a license for Ver 1 of Scrivener. More recently, I started using the Beta version and have been updating it as it expires.

After I started using Beta, I uninstalled Ver 1, but I decided I want to keep Ver 1 on my computer as a kind of backup. I just downloaded and installed Ver When I installed, it didn’t give me any indication whether it was a trial version or a licensed version, and it didn’t ask me for any license info.

How can I determine whether it’s a licensed version? Is there a way to retrieve my license key?
