How to determine OS version before installation

[Lawrence1030]

Hi,

I am using IS 2012 Premium and created a InstallScript Project. To meet the request, I have to check the OS version before the installation. I would like to use "Condition" to do it, but there is no entry for InstallScript project.

Is there any way to do that? I can use Script to do it, but it will cause failure when I try to pass ACK. Any input will be very appreciated.
