Ways to install Windows Vista SP1 drivers on Windows 7
Mark Minasi’s latest newsletter illustrates two workarounds that in most cases with get you out of jail
1. Run the installation in Windows Vista SP1 compatibility mode, right-click properties -> compatibility tab and run in Vista SP1 mode.
2. Extract the driver, in an elevated command prompt type pnputil -i -a name-of-folder\*.inf, like “pnputil -i -a c:\newdriver\*.inf.” The system will think about it for a moment or two and report that you’ve properly installed the driver. Then you can go ahead and install manually.
Great work Mark – like most this is a major concern for pre-retail adoption!
