Leica Flex Office/Geo Office Tools

I've got an old Leica TS02 Plus and need to get the data from it to my laptop. My boss usually does this but she's on holiday for the next couple of weeks so I need to do it myself. Unfortunately she's buggered off with her laptop which has the relevant software installed.

I've tried to find Flex Office or Geo Office Tools online but can't find them anywhere. Just a bunch of shady looking websites with names like leica-downloads-not-gonna-hack-you-honest.lol

Is there any software available that can talk to an old Leica TS02 Plus that I can download? Bonus if it runs on Linux as well as Windows 10. I can't see anything on Leica's website aside from the eye wateringly expensive stuff for new machines.

I've tried just hooking the machine up to my laptop but neither Windows 10 nor Linux seem to be able to see it.

(I've never had to download data from the Leica before so there could be something really elementary that I'm missing.)

Thanks in advance.
