PROWin7_32_v16.4 is a 32bit driver but you8 say at the start you are using win 7 64bit, try a 64bit driver. unlikely to be the cause but worth a shot.
Sounds to me like an irq conflict
Thanks for quick reply
Its just typing mistake its 64 bit driver only and i have verified that driver. and Otherwise instillation package doesn't go ahead.
and if i see in conflict windows its shows no conflicts ( i think its not irq)
