OK. I know!

It’s (the other one too) a lab pc for scientific instrument. It’s connected rarely, only for data transfer.

Do you confirm that from version 5 (or even previous versions) of the client, old operating systems are no longer supported? I was unable to find the information on the site, sorry.

Thank you very much.


Yes. 4.x works for older versions.
