>How to detect Vista 32 or 64 bit with OS() ?


Denis,

First make sure that you're running under WInXP or later, or WIn2k3 server or later. The IsWow64Process on MSDN http://msdn2.microsoft.com/en-us/library/ms684139.aspx

DECLARE Long GetCurrentProcess IN WIN32API 
DECLARE Long IsWow64Process IN WIN32API Long hProcess, Long @ Wow64Process
lnIsWow64Process = 0
llIs64BitOS = .F.
IF IsWow64Process( GetCurrentProcess(), @lnIsWow64Process) <> 0
	llIs64BitOS = (lnIsWow64Process <> 0)
ENDIF	
? llIs64BitOS
