Sometimes, driver manufacturers do not provide an executable file (.EXE) to install their drivers. Instead, they provide an INF file in a zip or rar file.
The first thing you need to do is unzip this file , remember where it is .
An INF file is short for INFormation file. This is a document that Windows “reads” to know how to install a driver. Following are the instructions to install a driver via its INF file.
Note: The steps below assume that you have already downloaded the new driver recommended by DriverIDentifier and unzipped its contents. (This is important. If the file is not unzipped and it’s contents extracted, Windows will not be able to detect the INF file.)
1. From the Windows menu, click Start.
2. Click System, choose Hardware, and then click Device Manager.
3. Click the device whose driver you want to update.
4. Right-click the device and then click Update Driver. This will open the Hardware Update Wizard.
5. Click No, not this time and then click Next.
6. Click Install from a list or specific location (advanced) and then click Next.
7. Click Search for the best driver in these locations.
8. Click Include this location in the search.
9. Click Browse and go to your driver file location (inf file – the location that you unzip the driver download file)
Tip: If the wizard finds the INF file, the OK button should be clickable (not grayed out).
10. Click Next.
11. Finish the Hardware Update Wizard.
12. Reboot your computer.
