Security warning after installing an update crashes FSX


Recommended Posts

On March 29 I purchased FSUIPC4 and installed it. As my FSX application opened I noted a window popped up asking if I wanted to run the application or not, I clicked on "Run This" or something to that effect. I entered FSX, found FSUIPC4, registered, etc. and all seemed fine.

:lol:

Last night I downloaded v4.0.9 and installed it over the prior FSUIPC4. When I started FSX the blue "Microsoft Flight Simulator X" screen appears but then and only briefly a smaller window comes up - something with buttons to "Run" or "Don't Run" - it flashes for a fraction of a second, then disappears. And then the FSX program quits. All this taking only a few seconds to go through a complete cycle.:cry:

I do not seem to be fast or coordinated enough to click on the "Run" button when the window pops up - though I've tried. Then of course, it might be that even if I hit "Run" in time, the FSUIPC4 might be causing the crash.

If I pull all the FSUIPC4 files out of the FSX Modules directory, then FSX loads fine, just as it did with the prior version of the FSUIPC. I could not find the prior version to revert to on line.

I just had this PC built so that I could play FSX (XP Pro, several Intel Core2 Xeon Quad / Extreme CPU's with 8mb Cache - 16 processors, with two 1 Gig Nvidia Graphics Cards, 4 GB of DDR2 SDRAM 667 MHz Ram, etc,.), or I may be doing something wrong. Please advise.

This is due to the combination of another SimConnect add-on you have installed, one which improperly asks SimConnect for data before FSX is ready, and a bug in FSX which causes the crash when it produces its Security question at the same time.

When you find the culprit add-on I'd be grateful if you could contact the author and tell him of this. I cannot fix anything in FSUIPC because FSX is crashing before it is even loaded!

The same would occur with any new add-on, by the way. You can easily stop FSX coming up with this prompt for my new versions if you tell Windows to trust me "Peter L Dowson". Check the drop down when you do get the prompt to read. I paid for a proper security code-signing licence specifically so you could do this, it would be a shame to waste it.

Just as I posted my Q, I came across a prior posting that mentioned pulling the add on "Autothumbnail". So I cut the directory "Autothumbnail", reinstalled the FSUIPC4 4.0.9 files, and FSX came up as it should. The windows appeared asking me to verify that I want to run the files and trust Pete Dowson, etc.

Then I quit FSX and reinstalled "Autothumbnail", the restarted FSX and the program came up just fine. I checked the "Add Ons" Menu and both FSUIPC4 and Autothumbnail appear to be working just fine.

Could it be that for the time being I will need to uninstall all add ons to accommodate another?

Well, thank you again for an invaluable - and working - add on for the FS Community :D

Not all add-ons, only those which ask SimConnect for data before FSX is ready to supply it, like, it seems, AutoThumbnail, which has affected three users posting here so far.

And if you install a signed add-on, like FSUIPC4, you can tell Windows to trust the publisher so that prompt doesn't occur with any further new installs from the same one.

I'm hoping that the problem in SimConnect / FSX will be fixed in the SP1 update, but in case it isn't it is a good idea to tell the authors of the relevant programs that they really need to wait for a "SimStart" event before asking for data on objects. It isn't a difficult change -- I did it in FSUIPC4 as soon as we learned of this problem.

Pete
