Last reviewed: August 21, 1996

The information in this article applies to:
  • Microsoft Windows 95

IMPORTANT: This article contains information about editing the registry. Before you edit the registry, you should first make a backup copy of the registry files (System.dat and User.dat). Both are hidden files in the Windows folder.

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

To enable the Install command for .inf files, use any one of the following methods:

  • NOTE: For information about how to edit the registry, view the Changing Keys And Values online Help topic in Registry Editor (Regedit.exe). Note that you should make a backup copy of the registry files (System.dat and User.dat) before you edit the registry.

    WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall Windows 95. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

    Change the "(Default)" value in the HKEY_CLASSES_ROOT\.inf registry key to "inffile" (without the quotation marks). Restart your computer for this change to take effect.

  • Restore the standard shell commands. To do so, click the Start button, click Run, type the following line in the Open box, and then click OK:

          rundll setupx.dll,InstallHinfSection DefaultInstall 132
          c:\windows\inf\shell.inf
    

    NOTE: Type the above line as one long line. If you installed Windows 95 in a folder other than the Windows folder, adjust the command accordingly.

    After hard disk activity stops, restart Windows 95.

  • 1. Start Windows Explorer.

    2. On the View menu, click Options, and then click the File Types tab.

    3. In the Registered File Types box, click Setup Information, and then

          click Edit.
    

    4. Click New, type Install in the Action box, and then type the

          following line in the Application Used To Perform Action box:
    

             c:\windows\rundll.exe setupx.dll,InstallHinfSection
             DefaultInstall 132
    
          NOTE: Type the above line as one long line. If you installed
          Windows 95 in a folder other than the Windows folder, adjust the
          command accordingly.
    
       5. Click OK Until you return to Windows Explorer.
