I've spent hours on Forums searching for a fix , plus, I'm on my second full download (phew!) in two days to eliminate a corrupt file. Carefully Installed as per instructions both times. careful with un-install as per instructions and I ALWAYS 'run as administrator".

My system
Windows 7/64
Intel 2600 K
8 MB RAM
Asus Rampage Extreme M/B
Three Nvidia cards (not SLI) running 7 LCD panels
Matrox Triple Head 2 Go
Full GoFlight Airline Pilot system
FSX fully loaded on "C" drive - Raid '0' - no problems at all. Active Sky XGraphics, ORBX, many addon aircraft, FSUIPC.
Prepar3d Installed on "D" drive (nothing else on drive and no add-ons at all) Single 7200n Seagate HDD

As I said FSX runs beautifully (well, as beautifully as FSX can) but I cannot do anything with Prepar3d, not even calibrate my flight controls without a crash every time I try to save settings. HELP.

I"ve been trying to use Prepar3d since it came out and have not had $9.95 worth of joy yet! Almost about to give it a miss and put up with FSX. Only trouble is there are heaps of you out there who are having joy, so I live in hope and I certainly want to support the project as it is the future. I fly real world aircraft too.

Hi,

i had the same problem, even if i use "Apply" or "Accept".

I set prepar3d.exe to "run as administrator" and set "full access" for all files in the installation folder for my user-account.

Hi Adam,
Did as you suggested and I was actually able to change my resolution from default to 5040 x 1050 x 32 (TH2G ) and it saved! I just pressed "accept," and ignored "reply" on this occasion.
Unfortunately , it only did it this once and the previously reported anomaly returned with subsequent attempts to save any changes resulting in the same crash. Incidentally, all drivers are current.

Hi Jan. Double checked all permissions on (D:) including Prepar3d and all "owned" by me - David-User. As I said, I always activate the .exe file as administrator. No change to symptoms when I try to save settings.

Hi Jan. Thanks.
I have checked the accounts and it is as you have stated. I do not have any other accounts. For this exercise I have deleted all accounts and am using the Administrators account with Guest Off (and that NVidia acount deleted UpDatusUser). I have ensured that I have FULL CONTROL on C:, D: and the Prepar3d Folder in D: plus the P3d.exe file which I always "run as administrator." I have checked until I'm blue in the face and I cannot find anything that I do not have FULL CONTROL over when it comes to programs BUT! When I look at the Properties of the Prepar3d Folder, the "Read Only" box is ticked, even though I untick and it goes through the process of applying attributes, when I close it and reopen, it is ticked again??? I'm obviously missing something but I cannot think what it could be. Happy to TeamSpeak. I'm in Brisbane, Australia GMT +10. Cheers.

...in conclusion after a long and pleasant chat session with "down under" it results in the observation that the initial downloaded Academic zip files did not pass the MD5 check sum test.
Unless the files where corrupted before installation, the sim functioned, including multi play session. However, saving any changes made the sim crash on the module kernelbase.dll
Which brings me to the urgent advice to anyone with fatal error or appcrashes to check at least the md5 checksum of any downloaded zip
Read this http://janvaane.org/virtualfsx/?page_id=6242 how to execute a MD5 checksum.

Hi Adam, hi Jan,

i checked the md5sums with FastSum as jan described it above.
The md5 sums of my zip files are ok.
I tried to analyze the crash with sysinternals process monitor, but can't find any special of interesset.
It seems that dxdiag uses kernelbase.dll (succesfully) while prepar3d.exe crashes.

My installation crashes not only if i change some options. I allthough get a CTD, if i change time or date.

If it's helpful, i can send a process monitor logfile.

Greetings Matthias

Hello Jan,

i set "run as administrator" at the compatibility tab at properties of prepar3d.exe.

My installation path is
E:\Program Files (x86)\Lockheed Martin\Prepar3D

My account has full rights on the whole drive E:
The same to the appdata folder for prepar3d.
