Cannot export the lexicon

Problem

k.c. reported:

I tried to complete a File : Export : Lexicon for the first time and immediately got a Range Check Error. How can I fix this please?

 "Cannot copy g:\supermemo_kai 20240413\supermemo db2\registry\Lexicon.lst to C:\Supermemo backups\(((Backup of supermemo db2 created on 2024-04-13 16-27-00)))\registry\Lexicon.lst 

 Range check error"

Answer

This problem could not be reproduced. As it seems to be based on a file lock, you can simply try again after restarting SuperMemo (or even the computer).

The problem has never been reported before.

Comment

Ever since incremental reading, lexicon is less popular and not built by default. It is thus far less tested in real life. The export code has not been changed for years. It is possible there might be some old bug lurking.
