First there is the supplemental driver install. If your DVD doenst have it available you can use Beta 1 DVD to get the supplemental driver install to start.
2nd there is the Device Manager. With the Device manager there are a couple of options.
1. you can point it to your XP partition and see if it will install from XP
2. extract the executable with WinRar. In the extraction you should find a .inf file. In Device Manager point it to that file and see if that works.
3. point the Device Manager to your install CD and see if it can install the drivers that way.
3rd. Try to install the executable in XP compatability mode. To get there right click on the executable and go to properties. Flip thru the tabs until you come across the compatability menu. Drop it down to XP.
4. Try to manully force the driver install. Manual Driver Installation
Manual installation of device drivers may be necessary if drivers are not successfully installed by running setup in XP Compatibility Mode. This is accomplished from Device Manager (right click Computer>Manage), by right clicking on the device>Update Driver>No, not this time>Next>Install from a specific location (Advanced)>Next>Include this location in the search>Browse – to the location containing the required drivers. It is necessary to extract the .inf, .sys and .cat driver files to a folder using a tool such as WinRar before you can manually install your drivers in this way.
These are as far as i have seen the only ways to install drivers for Vista. I just made this so hopefully if ysomeone has an issue with Driver installs they can read this and try them out and if none of these options work then ask for help.
