deny all operating systems except for a few

[jweinraub]

Hello,

I recently wrote asking how do I deny OS's. However, after talking with a few people and more scenarios occurred to us. All these what-ifs.

So I would like the installer to FAIL for EVERY OS, but ALLOW a few...

my pseudo code is as follows: (this is be rather phpish/crap)

Function .onInit

switch ($operatingSystem)
{
case "Windows 2000"; // all editions
goto success;
break;

case "Windows XP" // only pro version
GetVersion::WindowsType
if $R0 == "Home"
goto failure;
else;
goto success;
break;
case "Windows 2003"; // all editions
goto success;
break;
default:
goto failure;

...

function failure
msgbox "your $os is not supported. please call 1-800-555-5555 for additional support."

... pretty much 95,98,me should fail...so should vista all editions, and i dont know but XP 64-bit should fail too.

thanks for any help you can offer me :-)
