In my case it works fine.
Copy / pasting outputted
E:\ProgDB\EmEditor\Macros\Toggle_read_only.jsee \t 0x00000000
E:\ProgDB\EmEditor\Macros\insert_date_only.jsee \t 0x00000000
E:\ProgDB\EmEditor\Macros\insert_date_time.jsee \t 0x00000000
E:\ProgDB\EmEditor\Macros\insert_date_long_time.jsee \t 0x00000000
E:\ProgDB\EmEditor\Macros\delete_between_bookmarks.jsee \t 0x00000000
Where \t is the tab character.
It looks like the \t and 0x00000000 can be omitted from the list.
Pasting allows me to run the Macro, but when trying to edit them I get your “The following files do not exist error”. → Restarting EmEditor fixes this.
