* Parameters:
* installScope [I] the scope which was used in AddGame/InstallGame call
* gameInstanceId [I] game instance GUID. If NULL, then only

*
* Name of game's registry key always follows patterns below:
* When game is installed for current user only (installScope is GIS_CURRENT_USER):
* HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\
* GameUX\[user's security ID]\[game instance ID]
*
* When game is installed for all users (installScope is GIS_ALL_USERS):
* HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\
* GameUX\Games\[game instance ID]
