FSX-MS Uninstall and Reinstall FSX SP2?

[ark 1,288]

If I uninstall and reinstall SP2 for FSX, will I have to also reinstall most addons?

I am thinking of trying this because of a strange display problem. I have FSX Deluxe(SP2) and FSX-SE on the same machine (Win10/64) and use Lua scripts with FSUIPC to display things like a/c checklists, selection menus, etc. In FSX when I activate a script to display a list of items I can see the list 'grow' in size, e.g., 10 short lines of info do not flash on the screen as a single display unit as expected, but instead you can see the list grow or scroll down (as if quickly pulling down a window shade), and sometimes there is jitter as the list builds. Once complete the display is stable, and any sublists displayed by making a selection from the original list display instantly as a single unit as expected even if the sublist is bigger than the original list. Others using the same scripts with FSX don't see this problem. And with FSX-SE on my machine when running exactly the same scripts, all displays appear instantly as a single unit, there is no scroll down effect or jitter, everything works as expected. I have experimented a bit with different Nvidia display drivers to no avail. Pete Dowson (FSUIPC developer) says FSUIPC simply passes the info for dispIay to SimConnect so I have tried reinstalling the three versions of SimConnect associated with FSX Deluxe, but the problem persists. So I'm wondering if there may be a Registry issue or some kind of a problem between SimConnect and Win10 that the reinstall of SP2 may fix. Admittedly a shot in the dark. My Win10 account is Admin, UAC is off, and FSX is elevated to 'run as administrator'.

Thanks for any ideas,

Al

Why not just stick with FSX:SE? It's a better version of FSX anyway and includes the Acceleration pack.

You can uninstall/reinstall Acceleration or SP2 and you will not have to reinstall any addons.  It does not affect your fsx.cfg or scenery.cfg.

Yes, that's an option, but I have not kept things (addons, etc) up to date with FSX-SE  and if I have to go through a lot of reinstalling, I would probably just go over to P3D and do it there since it looks like P3D is the way to go for the future. And, I'm just curious as to what might be causing this problem with FSX.

Thx,

But if you stuck with FSX:SE, at least you wouldn't have to re-buy the add-ons as you would with many of them for P3D.

Jim,

Thanks very much for the info -- that's what I was hoping to hear.   I have already tried letting FSX rebuild the dll.xml file and have compared the fsx.cfg with fsx-se.cfg, so I will give reinstalling SP2 a try and see what happens wrt the display issue.

Yep, that's certainly a valid point and something to be considered.

Just to be sure everyone understands, my comments were related to FSX (boxed) and not FSX-SE.  I believe it is impossible to remove just SP2 or Acceleration from FSX-SE.
