Problems generating accurate real world real time weather

The implication of your reply is that I'm lying. So:

Maybe it's because I have a Bachelor of Science in Computer Information Systems, and understand a little bit about how poorly programs interact with each other in a Microsoft-based system. It's a Microsoft OS, and the primary program being used is Microsoft's flight simulator. That just begs for problems. And in fact these problems appear all the time... expensive payware aircraft and add-on programs continually have small glitches in which the only solution seems to be "re-install, maybe that will fix it... it should work."

To be perfectly honest, it's actually NOT an option on my system because I've disabled User Access Control because it causes too many problems. With it enabled I had to go in and manually set Run as Administrator for almost every program on the computer. (As a side note, this doesn't even make any sense considering the ONLY user on that computer IS the administrator account.) So, with UAC disabled, you can't select Run As Administrator, because it actually already recognizes you're logged in as the administrator. Programs work much more smoothly like this. Turning on UAC just to enable Run As Administrator is redundant. So, this is not the problem.

I've run ASA several different ways. The problem as I can see it is that there is a major mis-interpretation as to the use of Force Destination Wx Zone. In real life, when you descend into an airport that is calling low ceilings, low vis, and possibly some sort of precipitation, you don't ever see the airport until you break out at the end of the approach. ASA is trying to simulate the conditions by lowering the visibility at the last second. Every time I do one of these approaches using ASA I can see the airport perfectly until I get to the final approach fix, roughly 5nm out, then suddenly the airport disappears into low vis as ASA drops the vis down. This is nowhere NEAR realistic. Also, it seems that ASA doesn't draw the lowest cloud layer either. If there's an OVC001 layer in the METAR, there should be clouds covering the field. Even if the reported vis is 10sm, you won't see the runway until you break out of the clouds at 100ft. That is what I should see around the destination airport without Force Destination Wx Zone checked. With it checked, those conditions should appear everywhere within 80nm, according to the popup help in ASA. This would be a great feature if it worked. Like someone else said, even if it were reduced to something like 30nm it would be great. The idea being that fast-moving high-flying aircraft will descend into these conditions quickly and want to be able to see the conditions as they approach the area.

ASA is doing a great job of creating lots of enroute weather. But destination weather needs major amounts of work. Especially considering the "fun" part of the trip is doing that approach down to minimums. It's hard to do it to minimums if the expensive weather engine program isn't drawing the weather accurately. It is becoming apparent that this is a programming flaw that needs to be patched. From what I can tell there is a section of code looking at the altitude of the aircraft and drawing weather mostly in the vicinity of that aircraft so that IFR fields are appearing as clear skies because the aircraft is still several thousands feet above field elevation. This isn't good at all. Waiting until the last second to mimic the conditions with ONLY low vis isn't a good option. And yes, I have cloud layers set to maximum in ASA. Low level cloud layers should be getting drawn. I am very close to giving up on ASA until a new patch comes out. I got better destination weather results with FSX's default weather engine.

Enroute weather alone isn't enough to make this program worth the money I've paid for it (please keep in mind that the price tag on ASA is equal to what I paid for FSX). The destination weather needs to be fixed. This is supposed to be a comprehensive weather program covering origin, enroute, and destination.
