In the comments there's much ado about the app being 32-bit only. That means it won't work on 64-bit apps -- Not that it won't work in 64-bit Windows. That said, you're probably not going to have much luck uncovering the passwords with either 32 or 64-bit apps, but if you wanna try, Nirsoft has something to do that for free.

XenArmor uses a 3rd party installer, so you'll get some extra junk from the install. A Caphyon folder's added to ProgramData, you'll get a XenArmor folder added to the user AppData\ Roaming folder, and a few minor additions to Windows\ Installer. The registry gets 7 new keys. Copying the roughly 6MB app from my VM to regular Windows it seems to work fine, avoiding all that -- one registry key is still needed to store the activation key.
And for the record, neither this GOTD or Nirsoft's app did any good with Windows 10 Mail.
