When I attempt to open Chief Architect, I receive one of the following errors:  

  • "LoadLibrary failed with error 87: The parameter is incorrect."

  • "LoadLibrary failed with error 126: The specified module cannot be found."

How do I resolve this?


These error messages typically occur when your system is having trouble properly detecting your AMD graphics card.

In most instances, this can be resolved by updating or reinstalling the AMD driver associated with your graphics card. To update your AMD graphics card driver, please see the following AMD website: https://www.amd.com/en/support/download/drivers.html

Note: For further assistance on updating your graphics card driver, please contact AMD.

Once the graphics card driver has been updated or reinstalled, reboot your system.

You should now be able to launch the Chief Architect program successfully.
