TL;DR... The few comments on the download page talk about the app being 32-bit only, though the feature list says both 32 & 64-bit, so I took a look, and both 32 & 64-bit apps are included.
When you visit the page for the key on XenArmor's site you fill in your email, check the box for a CAPTCHA, and click the button -- you'll get a new page showing the key and a link to download the setup file that's the same size as the file you downloaded from GOTD. I used that 2nd, downloaded setup file.
Installed in a Win11 Pro VM that was reset to its condition just after the March Patch Tuesday updates, & then had all available updates installed. XenArmor Asterisk Password Recovery Pro has 2 executable files [.exe] in its C:\Program Files (x86)\ XenArmor\ AsteriskPasswordRecoveryPro\ folder, AsteriskPasswordRecoveryPro32.exe and AsteriskPasswordRecoveryPro64.exe. One is obviously the 32-bit version, the other 64-bit -- the desktop shortcut links to the 32-bit version. You also get a Caphyon folder in ProgramData, and 4 files in Windows\ Installer\. I recorded a total of 587 new registry entries, most of them having to do with caches -- you get 5 keys related to the Caphyon installer, an uninstall key, and 2 XenArmor keys.
