I have updated 32-bit Vista Home to 64-bit on a Dell i1720 laptop. I have loaded the required 64-bit Nvidia and WiFi link 4965agn drivers and they work fine. But, for the life of me I cannot get the 64-bit Broadcom drivers to load. The Broadcom FAQ warns not to use Device Manager to update these drivers. Instead, in bold letters, it says to use the latest Driver Installation Software. I have scoured the site for this app but failed to find it. I've concluded that I must be misunderstanding the instruction. Has anyone completed this operation and if so where is the app that allowed you to continue. Or, is there another interpretation?
