opel diagnostic tool

i find a good diagnostic tool for Opel OP-COM (http://www.diagtools.de/wholesale/opcom-2010v-can-obd2-opel.html) PC based Opel diagnostic
VERSION: 2010.08
OP-COM is a PC based diagnostic program.
It covers almost all Opel cars, even new cars with CAN-BUS based diagnostic, such as Vectra-C, Astra-H, Zafira-B.
The program lets you to read out and clear fault codes, shows you live data, lets you to perform output test.
The program supports many control units, like Engine, Automatic Transmission, ABS, Airbag, Engine Cooling module, Instrument Cluster, Electronic Climate Control, Body Control Unit,

That is a good obd 2 tool but on the site I don't see the pc requirements (processor, ram and hard disk space needed). Another thing, on the description should be mentioned what opel cars can be diagnose with this tools and from what years.
