 Module Name:

   ShockwaveLocation.cpp

 Abstract:

   In Encarta Encyclopedia 2000 J DVD, Shockwave is accessible only by installed user's HKCU.
   \WINDOWS\System32\Macromed\Director\SwDir.dll is looking for Shockwave location in HKCU.
   For other users, this shim will create Shockwave location registry in HKCU if Shockwave folder exist
   and not exist in registry.

   Example:
   HKCU\Software\Macromedia\Shockwave\location\coreplayer
   (Default) REG_SZ "C:\WINDOWS\System32\Macromed\Shockwave\"
   HKCU\Software\Macromedia\Shockwave\location\coreplayerxtras
   (Default) REG_SZ "C:\WINDOWS\System32\Macromed\Shockwave\Xtras\"

 Notes:

   PopulateDefaultHKCUSettings shim does not work for this case 'cause the location include
   WINDOWS directry as REG_SZ and cannot be a static data.
   VirtualRegistry shim Redirector also not work 'cause sw70inst.exe does not use Reg API
   and use SWDIR.INF to install in HKCU.
