I have trouble using the winqueryreg function.

I do not have problem using the example :
winqueryreg 'HKEY_CLASSES_ROOT' 'mwsamp.mwsampctrl.2\clsid'
and even if I add new key to HKEY_CLASSES_ROOT , I can read it perfectly.

However, if I am trying to read key from HKEY_LOCAL_MACHINE he cant get the correct key:

val = winqueryreg 'HKEY_LOCAL_MACHINE' 'Software\widemed\scripter' 'Stop'
the error is
??? Specified key is invalid.

to return a value you need to use the functional form of winqueryreg eg:

>> val = winqueryreg('HKEY_LOCAL_MACHINE', 'SOFTWARE\Microsoft\Windows\CurrentVersion', 'ProgramFilesDir')

val =

C:\Program Files

Good Luck,
