Printmaster 18.1 on Windows 11

My wife has been using Printmaster for over 25 years, and for the past several years, she’s been using version 18.1. When it stopped working recently, she enlisted my help. It turns out the desktop shortcut not longer functioned — it gave an odd install error. When I created a link to the executable, and pinned that to her toolbar, it worked — it functions again.
