How to EXPORT ALL of the Orders

-- HikaShop version -- : 3.0.0
-- Joomla version -- : 3.5.6

My client would like to EXPORT all of the Orders for import into their CRM.
There are over 4500 of them, so doing it at 100 at a time does not make any sense.

Yes, the Display dropdown does show ALL, but selecting it does not allow for Export.
The page just refreshes with only 100 selected.

Any help would be great.

Thanks.

I tried that, I just get the screen below.

Ah, it is a darn memory allocation problem.
php.ini says 512M but the local variable is showing only 64M!

Back to the host...
