 Module Name:

   CUSeeMe4.cpp

 Abstract:

    This DLL fixes a profiles bug in CU-SeeMe Pro 4.0 setup where it only adds some certain
    Reg values to the per-user hive (HKCU) instead of putting them in HKLM.

    We don't actually hook any functions, instead, we just copy the regkeys after setup finishes
    when our process detach is called.

 Notes:

 History:

    08/07/2000  reinerf  Created
    11/29/2000  andyseti Renamed file from setup.cpp into CUSeeMe4.cpp.
                         Converted into AppSpecific shim.
