How To Resolve the “Application Was Unable to Start Correctly (0xc0000017)” Error in Windows 11

That pesky “The application was unable to start correctly (0xc0000017)” message pops up when trying to launch programs or games on Windows 11, and honestly, it’s a real pain. Usually it’s because of memory hiccups or corrupted files messing with the startup. Not sure why Windows has to be so complicated about this, but there are a few tricks that might help get things back on track. Here’s what’s worked for some setups—no promises, but these steps are worth a shot.

Method 1: Jump into Command Prompt with Admin Rights

This step helps you poke around system files and see if there’s anything off with your Boot Configuration Data (BCD). If you don’t run as admin, most commands won’t do much or could fail silently. This is usually the first thing to try because it’s quick and straightforward.

Hit the Start menu or search bar at the bottom.
Type cmd and look for the Command Prompt app.
Right-click it and pick Run as administrator. This is essential—no short cuts here, or nothing will work.

Tip: On some machines, this step might throw a UAC prompt. Just accept it and carry on.

Method 2: Check the Boot Configuration Data (BCD)

This helps you see if there’s anything funky in the system’s startup configs, especially memory-related stuff. If your system has boot issues, it’s worth a glance here.

In the Command Prompt window, type or copy this command: bcdedit /enum all
Press Enter. The output can be long and kinda confusing, but if you see anything referencing badmemory, that’s a clue.

Why it helps: This reveals any suspicious entries related to memory issues stored in your boot configs, which could be stopping apps from starting.

Method 3: Remove Faulty Memory Entries from BCD

If you spotted anything related to bad memory, you’ll want to clear that out. It’s a bit of a shot in the dark sometimes, but it can fix startup hiccups.

Back in the Command Prompt, type this command: bcdedit /deletevalue {badmemory} badmemorylist
Hit Enter. If it works, that bad memory entry should vanish, potentially fixing your start problems.

Note: Sometimes this step doesn’t do anything or just throws an error, especially if there’s no such entry. Still worth trying.

Method 4: Reboot and Test

This feels obvious, but after messing with system files, a reboot can sometimes clear out the cobwebs.

Close the Command Prompt window.
Go to Start > Power > Restart.

Hopefully, that clears up the error, but if not, there’s more to try.

Extra Tips & Known Snags

Stuff that doesn’t always get mentioned but might matter:

Make sure Windows 11 is up-to-date—Microsoft drops fixes regularly, and an outdated system can be a culprit.
Run a full scan with Windows Defender or your favorite AV. Sometimes malware can cause these weird memory errors.
If the problem persists, checking RAM for faults with the Windows Memory Diagnostic tool is worth it. Just search for it in Start, then pick Restart now and check for problems.

Summary

Run Command Prompt as admin for system tricks.
Use bcdedit to examine startup configs.
Look out for or clear badmemory entries.
Reboot and test again.
Keep Windows updated and run malware scans.
Check RAM if stuff still acts weird.

Hopefully this shaves off a few hours for someone. It’s not rocket science, but Windows sure makes it a pain sometimes.
