I am also looking for this file, specifically for Windows 7... Wimdows 7 says the device was not successfully installed, it's listed as "Failed" and no cd drive shows up in My Computer... This is Win 7 64bit Ultimate on a Sony AR670 Laptop... sony's site has no win 7 drivers at all and no vista drivers, just a firmware update that doesn't run on a 64 bit system as far as I can tell, not that I need it... The built in cdrom.sys won't work for some reason even though I installed windows 7 from this drive to begin with. Lots of searching just brings me to scam sites wanting money to download the driver... I even paid one (will get money back from paypal) but of course it was a junk driver scanner, nothing useful.
