SimVar Extension

[TeaSea]

Suddenly one of the missions I have been flying is suddenly prompting me to load "SimVar Extension". From everything I can see it's loaded, but the mission isn't seeing it somehow.

Anyone have any ideas on this?

. . . .and I will go ahead and ask. . .what the heck is the SimVar Extension?

Well, sorta simply, I believe it's a module for using any missions created by the FS Addon Mission Editor.
I picked it up in some mission package a while back.
But I've disabled it. Really don't want it starting up all the time.

EDIT: Okay, I guess it comes with the free version of FSXME, the Mission Editor.
You can download that for free from here:

Sorry, should explain better, Dain is right in that it allows SDK to program variables into missions using the FS Addon Mission Editor. It is a component part of a lot of missions you run. Because I had downloaded the Mission Editor, and was using it to create simple missions, apparently the file had become corrupted.

The fix was to simply re-load, which Dain pointed out....Doh!

In theory loading the reloading the mission should do that as well....but I couldn't find in online anywhere.

In any case, problem solved!

Thanks!

Hi Folks

EDIT -
TeaSea posted while I was composing. :icon_lol:
P.S.
Reloading mission wouldn't solve,
as SimVar.exe is loaded on launching FSX.



TeaSea -
As Dain points out, SimVar.exe is a component of Jim Keir's FSXME package.

If as you say SimVar.exe is already running,
and the missions cannot find it,
then it's most likely a permissions or compatibility-mode issue.

For a definitive answer,
please post a question at Jim's FSXME forum at FS-Addon (http://forums.fsaddon.eu/viewforum.php?f=22),
or notify the mission's developer to do so.



Meantime,
and only guessing here -
are you by any chance using Windows 7 ?
and if so, is it the 64 bit version ?

With FSX and SimVar.exe not running,
you could try -
- Find SimVar.exe, (should be in C:\Program Files\Microsoft Games\Microsoft Flight Simulator X\Extensions\)
- Right-click on SimVar.exe
- Displays the Context menu
- Left-click Properties
- On the Comptibility tab.
- Tick the "Run this program in compatibility mode"
- From the listbox, select Windows XP (Service Pack 3)
- Click Apply, OK.

Now fire up FSX, and lauch one of those missions requiring SimVar.exe.

Does the mission work correctly now ?



Everyone -

SimVar.exe Overview
Think of SimVar.exe as an FSUIPC for FSX Missions.

SimVar.exe was originally only intended to
fill the gaps/repair broken aspects of the FSX mission system.

It now adds 20 commands to the FSX mission system,
and substantially extends the testable variables,
to approx 800 via FSXME/SimVar.exe,
versus 36 via the OPT, (60 in FSXA),
plus allowing you to set most writable variables.



It also works in a similar way to FSUIPC
listening for instructions or information
and injecting commands via SimConnect.

For a detailed explanation,
plus some mechanism demo missions,
please see - Expanding your Missions (http://www.jimkeir.co.uk/FSXME/Examples/SimVar%20Expo.html)



PS Important
To access additional SimVar.exe commands, (not present in first release).

Ensure you've downloaded/installed the latest FSXME build, (v 1.0.1766)
from the Latest Build thread in - Jim's forum at FS-Addon (http://forums.fsaddon.eu/viewforum.php?f=22).

That version includes an online updater.
Click Menu -> Help -> "Check for Updates"
which'll give you the current version, (v 1.0.1786)



You should also download Jim's MercRescue sample/demo mission
(from my link in that same thread),
as it demonstrates how to implement many SimVar.exe commands.

Good to know about the mission...it was Jim's Merc Rescue I was running when I had my problem.

Based on your comments, I believe my issue was a version problem. I ran the update and alles klar.

FYI, I run Win 7 at 32bit.

Love Jim's program too....
