Running win 98se amd2000xp 512mem epox8rda+

I can't load the driver conextant23880 from quick install disk- it keeps asking to install disk-after i put it in the dvd rom it says it cant find it- i uninstalled and tried again no luck- after 4 trys i e-mailed tech they just said its in the disk
Has anybody used this card and can tell me what i'm doing wrong?

Thanks BOB
