I found this in samples...

if (GetSystemInfo( OS, nvResult, svResult ) = 0) then
switch (nvResult)
case IS_WINDOWS : svResult = "Windows";
case IS_WINDOWSNT : svResult = "Windows NT";
case IS_WINDOWS95 : svResult = "Windows 95";
default        : svResult = "Fehler";
endswitch;
WriteLogLine( "OS: " + svResult );
endif;

However,  what are the results for Windows 2000, 2000 Server, XP Home, XP Professional, Me, etc.?

Thanks,
Doug

I'm not certain of the results you'd get for your function there, but I do some checking for OS in my installs... the way I do it is:

if (SYSINFO.WIN9X.bWinMe)
if (SYSINFO.WIN9X.bWinXP)
if (SYSINFO.WIN9X.bWin2000)

etc...

This probably isn't as pretty as a case logic, but it works and is very simple to deliver.

Straight from the IS 6 help files:

IS_WINDOWSNT = Operating system is Windows NT, 2000, or XP.
IS_WINDOWS9X = Operating system is Windows 95, 98, or Me.  

Hope that helps some!

That's exactly the way it should be done.

GetSystemInfo(OS, ...) stands for InstallShield versions 4 and 5. With IS 6, you are advised to use SYSINFO.WINxx.>member> to retrieve the exact version of the OS.

Though GetSYstemInfo(OS, ...) will continue working with IS 6, it gives you only poor results.

But I don't know how to distinguish W2K with W2K Server, or the XP variants.
