FSX ui.dll crash on startup

[Pelenor]

I haven't yet been able to play as my copy of FSX crashes just after the spash screen. The Event viewer logs seem to suggest that ui.dll is to blame.

If anyone has any ideas or a solution, that'd be fantastic.

I have exactly the same problem, also a crash with the 'ui.dll'. Did you find a solution yet?

Sorry to see that you are having an issue running FSX: SE on your PC. Have you tried validating your files through Steam?

To verify you game files please do the following:

1. Load the Steam platform and log into your account
2. Click the Library tab in the menu at the top of the screen
3. Click the List View from the view options on the top right of the screen
4. Right click on Microsoft Flight Simulator X: Steam Edition to bring up a popup menu
5. Click on Properties from the popup menu to bring up another popup box
6. Click on Local files from the popup box menu
7. Click on Verify integrity of game cache from the Local file options
8. Wait for the progress bar to finish verifying your files. Additional files may download
9. Restart Steam
10. Restart Microsoft Flight Simulator X: Steam Edition

We have a new update which will be available for FSX really soon and will makes the game more stable in general so that should also help.

Please give that a go and let us know how you get on. Are you running any third party add-ons or mods in your game?

same UI.DLL fatal error on new Windows 8.1 installation on Lenovo Y510P. first thing I installed was FSX. bad deal . what is up ?

[Pelenor]

Thanks for the tips, Martin. Tried both methods and I'm still getting the same issue - I'm not running any third party mods/addons, just the base game.

Run as Admin?
2 or 1 Monitor?
All Drivers are up to date?

[sdhyett]

I too have been getting crashes when about 30% into loading a flight.
Faulting modules are shown in Appcrash as being either util.DLL, mscvr80.DLL or ntldll.dll. (see my earlier post on page2 of this forum).
Crash occurs when loading Horizon VFR GenX photo scenery. Normally loads OK when such scenery is disabled. Have already reinstalled the scenery and ms c++ resist files, but to no avail.
All sliders are relatively low, no autogen when trying to load photo scenery.
I seem to recall that all was OK before last FSX Steam upgrade, if that's of any help.
Is it likely that the new beta will help with such crashes?

Two monitors, Drivers are all up to date.

[MasterFoo]

Yep, same problem here. Fresh install, even tried some registry cleaning methods to no avail. Any progress on that stability patch?

EDIT:

this solution helped: http://fsxeu.com/uiautomationcore-dll/

[SOLVED]

My FSX Steam edition running now smooth as butter :)

[Pelenor]

Thanks for the tip, MasterFoo. Gave it a shot, but unfortunately it didn't seem to work for me. Glad you had some success however.

My FSX doesn't even manage to get into game, it runs the "First run install" stuff each time then crashes as the FSX spashart comes up before the game-proper launches.

Still, glad some people are having some luck

Was having this same issue and stumbled upon another thread that worked for me Pear.

Try this, go into C:\Users\[YOUR USER NAME]\AppData\Roaming\Microsoft and delete the FSX folder, I was getting a weird crash at startup too and this fixed it.

AppData was hidden so I had to type in the file path on the bar up top and that worked.
I copied the FSX folder to my desktop in case this effed up my computer, then deleted it.
Started up FSX and it works now

Install MSXML 4.0 Parser and SDK.
Worked for ME (ME. That doesn't mean it will surely work for you)

run steam as admin, this will allow fsx to run with admin permissons

make sure your video card drivers are up to date, dont just assume they are, check to make sure

step 1, Install all the simconnects that DTG doesnt automatically install for you

keep in mind these are simconnect.msi files...just double click to install

where my FSX:SE is installed into my E:\ drive
there are actually (4) simconnects in FSX:SE

E:\SteamLibrary\steamapps\common\FSX\SDK\Core Utilities Kit\SimConnect SDK\lib
(install this one first)

E:\SteamLibrary\steamapps\common\FSX\SDK\Core Utilities Kit\SimConnect SDK\LegacyInterfaces\FSX-RTM
(install this one 2nd)

E:\SteamLibrary\steamapps\common\FSX\SDK\Core Utilities Kit\SimConnect SDK\LegacyInterfaces\FSX-SP1
(install this one 3rd)


E:\SteamLibrary\steamapps\common\FSX\SDK\Core Utilities Kit\SimConnect SDK\LegacyInterfaces\FSX-XPACK (YOU SHOULD NOT NEED TO INSTALL THIS ONE)
DTG now includes the install for the xpack since the last update/patch

the 2nd thing to do is install the C++ redistributable



E:\SteamLibrary\steamapps\common\FSX\_CommonRedist\vcredist\2005
there are 2 files here

vcredist_x86.msi (to install for 32 bit)
vcredist_x64.msi (to install for 64 bit)
just double click on the pertinant one for your system,should be 64bit


If you can't find them in your directory can you please go to this website, download and install these two files.

http://www.microsoft.com/en-us/download/details.aspx?id=3387
http://www.microsoft.com/en-us/download/details.aspx?id=21254



Please make sure you install them to the same drive where you have FSX installed. It doesn't need to be same folder or anything. Just the same hard drive.


just to make sure it is installed, the XML parser should also be installed, it should have been loaded already by fsx

E:\SteamLibrary\steamapps\common\FSX\Installers
msxml.msi
double click this file to install

It looks like the game needs the MSXML 4.0 dlls installed for x86 and they aren't included in the redistribution or are failing to install as part of the Steam setup on Win 8.1 Pro.

I downloaded the MSXML 4.0 SP2 and SP2 Hotfix from Microsoft and everything then worked. Get the files from:

MSXML 4.0 Service Pack 2 (Microsoft XML Core Services) - http://www.microsoft.com/en-us/download/details.aspx?id=19662
Security Update for MSXML 4.0 Service Pack 2 (KB954430) - http://www.microsoft.com/en-us/download/details.aspx?id=14623


install Directx 9.0c
E:\SteamLibrary\steamapps\common\FSX\_CommonRedist\DirectX\Jun2010

try those steps and try running fsx and see it it loads(the reason it keeps trying to reinstall everytime is that the sim is installed into a directory that has to have access via admin acct, (x86) usually)

@mikeytwc thank you very much, I went through so much trouble but finally your comment came to rescue.

[UniX]

Had the same problem on startup.
The clue from zCsab installing MSXML 4.0 was solving my problem!
Thank you very much :)
