How to read multisession data on any other dvdrom?

I am new to Nero. I burned a dvd and can read all the data in different sessions in the computer with Nero. But when I use another computer to read the data only the data in session 01 can be red.

When I check the disc info by using Nero, I get:
Dvd Session
Session 01 (2,610MB)
Track 01: …
Session 02 (1,701MB)
Track 02: …

I closed the dvdr already.
I realy do not know how to get the data in session 02 in any other computers.

Thanks in advance

You must install the Nero Multi-Mounter on the system where you can not access
the previous sessions. Link:
