OAX Software Version 2.80-01

From version V2.80 there are five installation files.

If you change from version V2.70 to V2.80, you only need the two files “Wersi Install” and “Software”. Even with updates where the last two numbers change, e.g. V 2.80-00 to V 2.80-01, only these two files are required.

More information can be found here.
