Another approach is to use the WMI registry provider:

#define HKLM 0x80000002

oStdRegProv = getobject("winmgmts://./root/default:StdRegProv")
cValue = space(255)

if oStdRegProv.GetStringValue(HKLM, "SOFTWARE\Classes\AppWare.Project\shell\Open\Command\", "", @cValue) = 0
    ? "Value is " + cValue)
endif

More info on using the provider in VFP is here.
