[MSIX] Apply DLL fixup

This fixup redirects dll loading IO calls to an appx/msix friendly location for dlls in the package.

When to use: When the packaged App is unable to run because it does not find dlls that are part of the package.

The fixup will be applied using the Package Support Framework (PSF) - an open source kit that allows applying runtime fixes to the repackaged Win32 app that fails to run in an MSIX container.

Important

Precondition: Open the MSIX package in MSIX Editor (see Open MSIX/APPX).

  1. Go to the Package Designer > Apps and fixups tab.

    msix-editor-apps

  2. Select New fixup > DLL fixup from the context menu of the application that fails.

    msix-editor-apps-context-menu-2

  3. Click Browse and choose the DLL file that can’t be found by the application when launched. Then, click Save.

    msix-editor-apps-fixup-dll-dialog
