Find app licence details?

[Cozzer]

Bit of a strange one for you PC buffs...

I have a choice of ebook compilers, but favour one in particular. The licence to use was purchased years ago - perhaps as far back as W95 - but it still works under Windows 11. So far, so good.
Over the years, the hardware has also changed of course. Various files lost/misplaced/uninstalled...
Came to use the ebook program this afternoon, and noticed the splash screen states "Licensed to..." but my name/trading name (whichever I registered) has disappeared. There's just a gap.
The app still works. It still compiles, but it looks a bit amateur to a viewer without the licence details. So I thought I'd probably find the missing info somewhere in the registry using regedit....
I thought I'd find info in HKey_Local_Machine\Software, but there's no sign of the program name at all... and yet it sits happily in C:/Program Files(x86).

Further searching using Find and F3 found various references to the program, but nothing I could identify as - or risk inserting - my licenced name.

Any ideas/clues, please?!

EDIT : Forgot to mention that the software is no longer available! The whole site has gone, so presumably the developers/sellers have moved on...

Leave it alone! Stop fiddling with it. You’ll only end up screwing it up beyond redemption. DAMHIKT

Had to look up DFWAB!

OK, gents, I bow to your better knowledge, and will leave it be.
Cheers!
