Thanks for your help but the programme has finally beaten me. I have FS9, X-plane 9 and 10 on this machine and they all run very well. I have both versions of FSX but neither work very well. So I will delete this programme, after three days of trying to get it to work - just to much hassle.

My specs are:

i5-2500k 4 core, 8GB Ram, Nividia GTX 560 Graphics card. Windows 7 64 bit.

I reckon this should run this programme ok but it seems not. Sad really as I would like to see Prepare3D in action. Anyway, FS9 goes good and X-Plane 9 and X work well so I must be content.

Thanks again
Danny

G'day Jorge. There is definitely evidence building that in it's present format P3D and FSX share computer resources even when not running. It is beyond my capabilities to determine where the conflicts are and/or why but I feel certain they exist.

Nope, no optimise through CFG. as I was not aware of this tweak or informed for that matter. I naturally assumed that the programme would install and work. Well it does work until I try to go into settings or weather and then it crashes. If there are tweaks should not they be in the install already so that you can use the programme from install.

Danny

No, sorry it just does not allow me to change anything. I am in windows mode but the whole of the screen and it looks like 768Xwhatever it was. The programme will run and I can change acf but that is all. If I want to do anything else it just crashes. I am redownloading again and will try to re-install but this might well be the last time for me.

Thanks

Danny

Make sure that if you have Windows 7 that you are running this as Administrator. Right click on the EXE and select 'run as Administrator'.

Ok, I have just re-installed and still get the same. Here is the log file:

Hope this helps.

aeronauto - if it installed correctly the download should not be corrupted - also the crash is coming from a different DLL.

it may be an issue with C++ libraries - run windows update and make sure everything is up to date

then

The System File Checker tool
To determine whether the issue that you are experiencing is caused by one or more system files that are used by Windows Vista, run the System File Checker tool. The System File Checker tool scans system files and replaces incorrect versions of the system files by using the correct versions.

To run the System File Checker tool, follow these steps:
Click Start, and then type cmd in the Start Search box.
Right-click cmd in the Programs list, and then click Run as administrator.

If you are prompted for an administrator password or confirmation, type your password or click Continue
At the command prompt, the following line, and then press ENTER:
sfc /scannow

and at last resort do this

Open CMD prompt and right click to run as administrator and then type in exactly as below substituting your windows login username where it says "username:" eg. "Andrew:F" or "Sarah:F"
takeown /f C:\Windows\System32\uiautomationcore.dll
cacls C:\Windows\System32\uiautomationcore.dll /G username:F
takeown /f C:\Windows\Syswow64\uiautomationcore.dll
cacls C:\Windows\Syswow64\uiautomationcore.dll /G username:F
Now you can just navigate to your syswow64 and system32 folders in windows explorer and after backing up the UIautomationcore.dll files just delete them from your computer. (Remember to delete the Uiatomationcore.dll file in ure FSX folder also if you installed it as the fix in other posts.)

let us know how you go. cheers

I did an update and then scannow and then removed the uiatomationcore.dll from both 32 and 64 folders, rebooted and went into window mode and alas it still crashes when trying to enter settings. I have now deleted 3D's cfg file and started again but again no go, it still CTD as soon as I try to enter settings.

Have tried to run in Vista compatability and XP as well but still no luck. So very frustrating.

Regards to all who have helped.
