Well I done installing 9.1 (even personal works)
and then upgrade from hd
Now I don't recomend you 9.2, I would rater chose upgrade to 9.1 Pro....
There is another way to export from DVD to CD's but it was a head ache for me....
Any way... Why don't you buy the cd ?
it is more usefull (I tough), some places in internet sells at 10dlls
(I will not refer to them here 'cause of - LQ Rules - , but if you ask me... I can give you the page where I buy)
