In many cases Windows will automatically update, but to check, head to Control Panel and search for 'Windows Update'. You can uninstall and re-installing the game or program you're trying to run - simple but sometimes the quickest and most effective way to get rid of the error. Tick the 'Run this program as an administrator' box, and click on OK. To do that, right-click on the shortcut or the actual executable for the game, select Properties and open the Compatibility tab. Try running the game or app with admin rights. When it's installed (or re-installed) reboot and try your app or game again. It sounds too simple, but it sometimes yields results. The first thing to try is restarting Windows. Typically you'll see this error when there's a mixing of 32-bit and 64-bit versions of Windows and applications. You may only need to one but in some cases you'll need a combination of them. If you see this error message: 'The application was unable to start correctly' it's probably because you're trying to run a game or program and there's something not quite right.īelow are various methods, most of which are simple, which you can use to try and fix the 0xc000007b error.
