Im trying to run dfittool in matlab but it makes MATLAB stop running and gives me the error General Error occurred in WebControllerFactory::create(). I've tried typing dfittool in the command window or opening it through the apps tab, but neither work.

Hi Yu Syn Wong,
It appears to me that you are facing difficulty in running “dfittool” in MATLAB. The error you are encountering, "General Error occurred in WebControllerFactory::create()", suggests there might be an issue with MATLAB's internal web components or graphics system, which are used by various apps including the Distribution Fitting Tool (“dfittool”). Here are few ways to troubleshoot and resolve this issue:
  • Restart MATLAB: If you haven't already, close and restart MATLAB. This can sometimes resolve transient issues that may cause such errors.
  • Check for Updates: Make sure you have the latest version of MATLAB installed.
  • Graphics Drivers: Ensure that your graphics card drivers are up to date. Outdated or corrupted drivers can cause issues with MATLAB's graphics rendering.
  • Disable Customizations: If you have any customizations or third-party add-ons installed, try disabling them as they could interfere with MATLAB's operation.
  • Reinstall MATLAB: If none of the above steps work, there may be an issue with the MATLAB installation. Consider reinstalling MATLAB after backing up any important scripts or data.
I hope this helps.
Best Regards,
Abhishek Chakram
