SYMPTOMS

When you use the right mouse button to click an .inf file, the Install command may not be available on the context menu that appears.

CAUSE

The Install command may not be available if the default association for .inf files is changed from the default value. This is often done by using the right mouse button to click an .inf file while holding down the SHIFT key, selecting a different program to open the .inf file, and then selecting the "Always use this program to open this type of file" check box.

RESOLUTION
