Modyfying .reg file

[Wingard]

Ok, here is one file from Evil Islands (there arent many of them and they dont seem to keep any important info) and one file from Etherlords 2 im trying to get into (holds informations about game's interface).

By the way i found something here: allods2.eu/en/files/
one file's description says that it allows to convert these .reg files into .xml (openable in Notepad) and other way round but i have no idea how to use this converter. :/ It was created for yet another game from Nival, i thought it may help.
