Providing Uninstall Functionality in an .inf Script

You can provide uninstall functionality in your .inf files by adding an Install section that removes the files, registry entries, and shortcuts, then adds your component to the list of programs that can be uninstalled from the Add or Remove Programs dialog box in Control Panel. An example is included in the IEAK Toolkit in the \<IEAK program folder>\Toolkit\inf\ folder.

To add your component to the Add or Remove Programs dialog box, add a new key and values under the following registry key:


HKLM,SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\app-name,"DisplayName",,"description"
HKLM,SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\app-name,"UninstallString",,"command-line"

description 
This string is displayed in the list box in the Add or Remove Programs dialog box.

command-line 
This is the command that is executed when the component is selected from the list box in the Add or Remove Programs dialog box. To execute a section in an .inf file, you can use the Setupx.dll InstallHinfSection entry point (described below).

The following sample AddReg entries add "My Test Application" to the list box in the Add or Remove Programs dialog box and executes the Remove_TestApp Install section in Test.inf:


HKLM,SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\Test,"DisplayName",,"My 
Test Application"

HKLM,SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\Test,"UninstallString",,"RunDll
setupx.dll,InstallHinfSection Remove_TestApp 4 test.inf"

Note Note 

  • Your installation script must copy the .inf file to the Windows\Inf folder when your component is installed. This is the default location that is searched when the Setupx.dll InstallHinfSection entry point is called.

  • Your uninstall script should remove the key you created under the Uninstall registry key so that your program will no longer show up in the Add or Remove Programs list box after it was uninstalled.
