If you’re seeing ‘The application was unable to start correctly (0xc000007b)’ error in Windows 10, you’re in the right place. I have seen this a number of times in computers from Windows XP all the way to Windows 10 Anniversary Update and it never seems to be the same thing twice.
The error is the typical Windows error that tells you nothing at all. Even checking Event Viewer doesn’t always tell you much, if anything at all, so general troubleshooting is the order of the day. Fortunately, there are a number of things you can do to get rid of this most annoying of errors.
Fix ‘The application was unable to start correctly (0xc000007b)’ error in Windows 10
As mentioned, there are a few reasons why you might be seeing this error, each requiring a different fix. Here are just a few things you can try.
Perform a clean boot of Windows 10
First let us try a clean boot of Windows 10 to see if it is a simple loading error that is causing the problem.
- Type ‘msconfig’ into the Search Windows (Cortana) box.
- Click the Services tab then check the ‘Hide all Microsoft services’ check box and then Disable all.
- Navigate to the Startup tab, select ‘Open Task Manager’ and disable all services with Status Enabled.
- Close Task Manager and select OK back in msconfig. This should reboot your device.
This process has been known to fix the issue in some cases. How I really don’t know, but it has. If it doesn’t work for you, try downloading the .NET Framework.
Re-install .NET Framework
Those of you who upgraded to Windows 10 rather than bought a device with it are more likely to see this issue. Windows 7 and 8.1 used .NET Framework 3.5 and so did many applications. Windows 10 uses .NET Framework 4.5 but didn’t think to include version 3.5 to make it compatible with older apps. This can be the root of the ‘The application was unable to start correctly (0xc000007b)’ error.
- Navigate to the Microsoft Website and download .NET Framework 3.5.
- Follow the installation wizard.
- Reboot and retry.
If that wasn’t the issue, there are also apparently files from Microsoft Visual C++ missing or that get corrupted in the upgrade to Windows 10. This affects games more than applications though, so if you’re seeing the error when trying to load a game, try this.
- Navigate to the Microsoft C++ Redistributable site.
- Download the latest file plus the 2010 files that include, msvcp100.dll, msvcr100.dll, msvcr100_clr0400.dll and xinput1_3.dll. There are both 32-bit and 64-bit versions of these files so make sure you have the right ones.
- Follow the installation wizard as directed.
- Reboot and retry.
In the vast majority of cases that I have seen, one of these three actions fixes the ‘The application was unable to start correctly (0xc000007b)’ error. If you have any other fixes that work, let us know in the comments section.
