Thanks for nice code i have found RegistryModify by ya110, I have built awesome administratived air application like Zinc Application. Thanks for root drive like C:\ or D:\ because they installed Windows OS into different like C:, D: or X: . I build simple NativeProcess and NativeProcessStartupInfo with reg.exe from \\Windows\\System32\\reg.exe.

That is nice trick like ' or " before string like this "SOFTWARE\\MICROSOFT\\...." Now I know how does Adobe Air work. Thanks!
