Add "Run as administrator" to MSP files

To add support for MSP files as well, I made some changes but won't work, please advise :)

Code:

[HKEY_CLASSES_ROOT\MSI.Package\Shell\RunAS]
"HasLUAShield"=""
[HKEY_CLASSES_ROOT\MSP.Package\Shell\RunAS]
"HasLUAShield"=""
[HKEY_CLASSES_ROOT\MSI.Package\Shell\RunAS\Command]
@=hex(2):22,00,25,00,53,00,79,00,73,00,74,00,65,00,6d,00,52,00,6f,00,6f,00,74,\
  00,25,00,5c,00,53,00,79,00,73,00,74,00,65,00,6d,00,33,00,32,00,5c,00,6d,00,\
  73,00,69,00,65,00,78,00,65,00,63,00,2e,00,65,00,78,00,65,00,22,00,20,00,2f,\
  00,69,00,20,00,22,00,25,00,31,00,22,00,20,00,25,00,2a,00,00,00
[HKEY_CLASSES_ROOT\MSP.Package\Shell\RunAS\Command]
@=hex(2):22,00,25,00,53,00,79,00,73,00,74,00,65,00,6d,00,52,00,6f,00,6f,00,74,\
  00,25,00,5c,00,53,00,79,00,73,00,74,00,65,00,6d,00,33,00,32,00,5c,00,6d,00,\
  73,00,69,00,65,00,78,00,65,00,63,00,2e,00,65,00,78,00,65,00,22,00,20,00,2f,\
  00,69,00,20,00,22,00,25,00,31,00,22,00,20,00,25,00,2a,00,00,00

Just curious, since the .msp files are patches [versus .msi which are installer files] wouldn't it be just as easy to right-click one and choose Apply to get it installed?

This question can be asked for MSI files as well, so we can say that doing so for MSI files is also useless, since eventually we'll get to the Admin mode when needed even if we don't run MSI files as Admin!
