 Module Name:

    PrintMaster4.cpp

 Abstract:

    Force mfcans32.dll to not have the read-only bit. Many HP systems shipped 
    with this turned on as a kind of lightweight SFP. However, the unpleasant 
    consequence is that PrintMaster doesn't install.

 Notes:

    This is an app specific shim.
