Try drivers from here:DRIVERS Vista32 Vista64 /EasyCAP USB 2.0 Video Capture Card/Adapter with Audio) » Sir Dekonass

EDIT
I didn't notice before your trouble with *.rar files http://www.vistax64.com/drivers/234681-vista-64bit-rar-files.html

So here you have drivers in *.zip format http://rapidshare.com/files/24988297...64bit.zip.html

And try reset Internet Explorer options Internet Explorer - Reset
