It works, but not with Win10's Mail app -- I could only get passwords from Outlook & Windows Live Mail [from win7].
Besides the program's XenArmor folder, you get a XenArmor folder in Users\ [UserName]\ AppData\ Roaming\, and a Caphyon folder in ProgramData. The Caphyon installer uses Windows Installer, meaning all the baggage of a typical .msi setup file. That means lots of extra registry entries for install/uninstall, with a {3BDED3EB-646A-4596-9DB6-94B58BE08CBE} folder & 2 files, 9c645.msi and SourceHash{3BDED3EB-646A-4596-9DB6-94B58BE08CBE} added to the C:\Windows\ Installer\ folder. The app itself uses a couple of XenArmor registry keys with few entries, one in HKCU\ Software\ and one in HKLM\ Software\.
