LyX ⇒ Saving personal Hunspell dict. when reinstalling LyX

[H_Strandin]

I have tons of technical terms in my Hunspell personal dictionary that I have to reenter when I reinstall LyX. I've tried to locate Hunspell's personal dictionary file in Windows, so I can preserve it, but failed. There is no path information in LyX, Windows doesn't know that Hunspell is installed, and searching the file system for "hunspell" gets me only some .xhp-files deep in some registry structure under [user]\AppData. (I don't know what those are.)

Surely someone else has had this problem, and knows how to save the personal dictionary between LyX installs?
