Cannot launch Inventor - Error: Access violation - code c0000005 (first/second chance not available)

I cannot launch Inventor Professional 2024 or any other version. I keep hitting an Access Violation error.

Application: Inventor.exe
Error: Access violation - code c0000005 (first/second chance not available)
Crashed Module Name:
Exception Address: 0x00007ff8095805e8
Exception Code: c0000005
Exception Flags: 0
Exception Parameters: 1, 7ff8676bb65c

My machine has an NVidia Quadro P1000 with the latest certified driver (528.49) [https://www.autodesk.com/support/system-requirements/certified-graphics-hardware/inventor]. I am running Windows 11 Pro with the latest Windows Updates applied. 

I have tried clean installing Windows to resolve the issue, but it persists. I have not been able to get much help from the support team.  The last I heard was that the case had been escalated to senior support specialists on May 8th, 2023, but I have not heard back despite following up.

I have also tried uninstalling all versions of .NET and reinstalling Inventor, but alas, no luck.

Would someone here be able to help?

Hi! I did a quick search on this type of error. It seems to be related to graphics card driver. Please uninstall the driver and install the prior one just for testing. Also go to Nvidia Control Panel and select "CAD/Studio" oriented profile. Disable any aggressive performance options.

Many thanks!

Hi there. Thanks for the reply! I removed the driver, installed the previously released version (DCH/WHQL 518.03), and tried applying a generic OpenGL profile/turned off all fancy feature settings in the NVidia Control Panel. No luck.

Is there a particular driver version you recommend? Also, there is no verbatim setting labeled "profiles" or a "CAD/Studio" setting in the Control Panel.

Hi! I sorry my memory is corruptive now. Indeed, there isn't a CAD/Studio profile in Nvidia Control Panel. Select the "Base Profile" or "3D App - Modeling AFR."

Another thing to try is to set Hardware option to Conservative. Since you cannot even launch Inventor, you cannot get to App Options. Here is the xml file to change. Go to C:\Users\%username%\AppData\Roaming\Autodesk\Inventor 2023\ and find "UserApplicationOptions.xml." Make a copy as backup.

Edit the xml file in Notepad and look for "Hardware." Replace the line with the following and save.

<Hardware GraphicsFeatureLevel="1" GraphicsOptimization="1"/>

Restart Inventor. Does it work now? The setting disable all performance oriented graphics option. If this works, it usually means something is wrong with your graphics system or settings. Normally, the default "Performance" option should just work fine.

Many thanks!

Since I have Inventor 2024 installed, I assume you want me to look at C:\Users\%username%\AppData\Roaming\Autodesk\Inventor 2024\. Unfortunately, that folder doesn't exist (or any Inventor folder, for that matter). I'm guessing it doesn't exist because Inventor has never successfully launched. It crashes immediately upon executing (e.g., there is no splash screen, just the error reporting dialog).

Update: I decided to tinker around, and after inspecting the .dmp file generated by the error reporting dialog in WinDbg, I found that Mirekusoft Install Monitor on my system was causing the access violation. After adjusting its settings, Inventor 2024 launched successfully without any issues.

Thank you for your time on this!
