Browser extension for zipForm Plus won't install in Edge

two likely causes. first, if the install link goes to the Chrome Web Store, Edge needs allow extensions from other stores switched on before it will take it: Edge menu, Extensions, Manage extensions, toggle at the bottom left. second, and more likely in an office, the browser is managed. type edge://policy in the address bar. if ExtensionInstallBlocklist or anything with extensions in the name shows there, IT has blocked installs and only they can allow that one extension. a spinner with no error message is the classic sign of a policy block.
