How to Fix an App That Keeps Crashing or Won't Open

The Problem

Chrome, Adobe, a game, or Office worked yesterday; today double-clicking does nothing or the window vanishes in a second. When every app stutters, the PC has a wider issue—freezing and crashing. One stubborn app is almost always that app's update, cache, or permission—not a dead motherboard.

Symptoms

  • Splash screen then instant close with no error.
  • Application Error or 0xc0000005 / 0xc0000142 codes.
  • App worked until a Windows or app update installed overnight.

The Fix: Step-by-Step

Step 1: Reboot and Run as Administrator (Once)

Right-click the app → Run as administrator. If it only works elevated, fix permissions or reinstall to the default path (C:\Program Files), not a random folder on D:.

Step 2: End Stuck Background Processes

Ctrl + Shift + Esc → Processes → end all instances of the app (e.g. Chrome, Acrobat, GameName) → try opening again.

Step 3: Repair or Reset (Microsoft Store and Some Desktop Apps)

Settings → Apps → Installed apps → find the app → ⋯ → Advanced options:

  • Repair first.
  • Reset if repair fails (resets app data—sign in again afterward).

For classic installers (Office, Adobe): open Settings → Apps → Modify or run the vendor's Repair from Control Panel if listed.

Step 4: Clear App Cache (Browsers and UWP)

  • Chrome/Edge: Settings → Privacy → Delete browsing data → cached images/files (or rename the profile folder after backing up bookmarks).
  • Microsoft Store apps: Advanced options → Reset as above.

Step 5: Compatibility Mode (Older Software)

Right-click the .exe → Properties → Compatibility → Run this program in compatibility mode → try Windows 8 or Windows 10 → check Run as administrator only if needed.

Step 6: Install Visual C++ and .NET Runtimes

Games and creative apps error with missing DLLs. Install Microsoft Visual C++ Redistributable (2015–2022, x64 and x86) and latest .NET Desktop Runtime from Microsoft's download site—official links only.

Step 7: Update or Roll Back the App

Update to the latest version inside the app or vendor site. If crashing started after an update, uninstall → download the previous installer from the vendor archive if offered, or wait for a patch.

Step 8: Check Event Viewer for the Real Error

  1. Win + R → eventvwr.msc → Windows Logs → Application.
  2. Find Error at the crash time—note Faulting module name (e.g. nvwgf2umx.dll = GPU driver).
  3. Update that driver from NVIDIA/AMD/Intel, not a random forum "fix."

Step 9: Reinstall Clean

Settings → Apps → uninstall → reboot → install fresh from the official site. Avoid leftover folders in %AppData% only if support tells you to remove them—back up licenses first.

Gaming-Specific Quick Checks

  • Verify game files in Steam/Epic.
  • Disable overlays (Discord, GeForce Experience overlay) one at a time.
  • Optimize Windows for gaming after the single title launches reliably.

When It Is Not the App

Multiple programs fail with the same 0xc0000005—run sfc /scannow and RAM test from the freezing/crashing guide. Antivirus quarantine may have deleted a shared DLL—check Protection history in Windows Security.
