Software Deployment

When I run Validation on my .msi, I get an ICE03 Error - "Value not a member of the set". When I look at the SDK, I see that, in fact, 40 is not a valid value (because "Disallow Advertise" = 8 and "NoUnsupportedAdvertise" = 32 -- the only combination that sums to 40 -- and this combination is not allowed as these attributes are mutually exclusive). Having said that, why does Wise Installer allow you to do this? And, how can I undo this now (the "Disable advertising if not supported by OS" checkbox - on the Feature Details dialogue box - is checked, but disabled, or grayed out)?
