firmware upgrade 2.6.2 -> 2.7.4

[GS]

I'm using S2 advanced 2.6.2

The "show on demand" feature in rev 2.7.4 should be helpful in testing the display.

Can 2.6.2 upgrade to a newer version or do I need to download and install 2.7.4 ?

Thanks in advance.

Download and run the new installer. Most settings will be kept. Your license seat will almost certainly be preserved, even if it asks you for the key again.
