If you are having any issues installing certain drivers in Windows 7, there are two methods you can try…
Install using Compatibility Mode
To install a driver using Compatibility Mode, right click on the Setup Application Stub (usually titled Setup.exe or whatever program you are opening to install the driver) and click on Properties, and then click on the Compatibility tab, enable Compatibility Mode and select “Windows Vista RTM” or “Windows XP SP 2” [it depends for which OS the drivers are compatible] from the drop down list, then click on OK and try again.
Install using Device Manager
If the above doesn’t work, use a utility such as WinRAR to extract the files contained within the self-compressed EXE package to a folder, and then use the Device Manager (Start > right click on Computer > click on Manage, and select Device Manager on the left hand side) to install the drivers. In Device Manager, simply right click on the device that you need to install a driver for and click on “Update driver software” and follow through the wizard, ensuring that you point it to the location of the files you extracted.
Isn’t it magic? ..
