There were a few questions in the download page comments, so I took a look at this GOTD...
Monitored in a Win7 32-bit VM, the installation routine, while not bad at all, is a bit excessive for what is essentially a 3 file app. To answer an earlier comment, the activation data is stored in a registry key, and the app won't run without it, so no, it is not portable. As far as keys go, it's dependent on how apps store their keys, *If* they store them at all... Office / Microsoft 365 is a subscription, so no keys, period. Photoshop is also a subscription, but it reported a [non-existent?] key anyway (?)(!). Don't know what to tell you re: Win10 -- XenArmor All-In-One Key Finder Pro Personal 2020 as well as Nirsoft produkey report a different Win10 key than what was used to activate Win10 Pro. XenArmor All-In-One Key Finder Pro Personal 2020 did find Ashampoo, Cyberlink, & quite a few GOTD keys.
Installation added a C:\ProgramData\ Caphyon folder, a C:\Users\ [UserName]\ AppData\Roaming\XenArmor\ folder, C:\Windows\ Installer\ 4e425.msi, C:\Windows\ Installer\ SourceHash{99443679-63B3-496F-B801-C8D68E1D53E0}, C:\Windows \Installer\ {99443679-63B3-496F-B801-C8D68E1D53E0}, along with the app's program folder. The registry gets 1 Caphyon installer key, a few Windows installer keys, a couple of XenArmor keys, and one unusual key: HKCU\ Software\ AI_RecycleBin.
That said, all the app needs are 3 of the files in the app's folder, and 3 registry entries to run fine -- I copied those files from the VM, and added [merged] the 3 registry entries in this copy of Win10, and it runs fine.
