I have downloaded Nero 220.127.116.11 for installation on Vista RC1 build 5600. I used md5sums to check the checksum after downloading and it was fine. But the install will only unpack the cab files and then stops executing and closes. The machine is a p4 3ghz with 1 gb ram. I am working with a 3 day old clean Vista install on a new WD 250 gb drive. Does anyone have anyone have any suggestions?
