Fix Application Crash Error 0xc0000142
Last updated: November 14, 2025
Resolve 'application unable to start correctly 0xc0000142' error, program launch failures, and DLL initialization errors
Overview
Error 0xc0000142 means an application could not initialize correctly, usually due to missing or corrupted DLL files, Visual C++ runtime issues, or system file corruption. This guide provides 6 methods to fix this common launch error.
What error 0xc0000142 means
Error 0xc0000142 shows up as “the application was unable to start correctly” and means a program failed during its own startup — specifically while it was trying to initialize, before it ever got to the point of actually running. Something the program needed in that initialization moment wasn't available or didn't behave the way the program expected, so Windows stopped it right there rather than letting it continue into a broken state.
The code itself is common across many different programs, which is exactly why it's less useful on its own than it looks — it tells you the program failed to initialize, but not why, and the why can be completely different from one instance of this error to the next.
How to tell it's this specific error
- A message containing “0xc0000142” or “the application was unable to start correctly” appears right as a program tries to open
- The program never gets as far as showing its own window — it fails before that point
- It happens consistently with one program, or sometimes several unrelated ones, right at launch
- The rest of the PC and other programs keep working normally
How serious is it?
Usually minor
A single program hitting this error occasionally, especially right after an update, is a common and usually low-risk hiccup.
Worth taking seriously
If several unrelated programs are hitting this same error around the same time, that broader pattern is worth paying attention to rather than treating each one as its own separate issue.
Why reinstalling the program doesn't always clear it
Reinstalling is the natural first move for a program that won't start, and it helps when the installed copy itself is damaged — but this error happens during initialization, which can also be tripped up by something outside the program entirely, and reinstalling the same program changes none of that.
Working out whether the program itself, or something it depends on at that startup moment, is really behind your specific instance of this error is what WindowsHelper is being built to help sort through.
