“The application was unable to start correctly (0xc0150002)” error
on Windows

Whenever I launch or reboot Windows, there's always an error message that pops up. It says "The application was unable to start correctly (0xc0150002)."  How can I fix it?

When Windows users see "Application Was Unable to Start Correctly (0xc0150002)" it signifies a program startup failure linked to missing system components or corrupted files or software conflicts. The application fails to start correctly because it cannot access crucial system libraries and configuration files to perform its tasks. When users face the 0xc0150002 error, they will receive a prompt to exit the program without any details of what caused it.

Users often experience this error as it affects various Windows operating systems during attempts to launch specific applications that need Microsoft Visual C++ Redistributable packages along with DLL files and system dependencies, although it can also occur at system boot up.

This problem might prevent both Windows built-in applications as well as third-party software from starting so users must examine their system's state and components. Several Microsoft Community members documented their encounters with this error which they associated mostly with uninstalled DLL files and system configuration breakdowns.

Why does the 0xc0150002 error occur?

The major causes leading to this error during application launch connect to system dependencies alongside software misconfigurations.

Failed regular or absent DLL files represent the primary reason behind application launch failures. Programs display the error after missing necessary DLL files or when these files become damaged and get deleted. The improper installation or incomplete provision of Microsoft Visual C++ Redistributable packages blocks applications from running because these packages hold vital components for numerous Windows programs.

System file corruption emerges as a potential cause when unexpected shutdowns combine with disk errors and malware infections. Windows core components which suffer damage prevent certain applications from accessing needed resources. Users encounter the 0xc0150002 error during program launch because their application configurations remain incorrect or they use outdated software versions that create compatibility problems.

How to fix the error?

System dependency errors and file or component corruption cause this problem so the solution often involves restocking fundamental packages together with damaged file repairs and software conflict verification. Using the [d1] PC repair tool helps fix system-related errors while maintaining stability because it automatically identifies problems and fixes these additional Windows components and dependency issues.

The following section offers structured instructions to resolve the issue along with directions for enabling affected application launch accurately.

Fix 1. Install all Windows updates

Outdated Windows components or device drivers can cause compatibility issues with certain applications. Keeping the system updated ensures that all necessary dependencies are present.

• Type Updates in Windows search and hit Enter.
• If updates are available, click Install updates.
• Otherwise, click Check for updates.
• If optional updates are available, install them as well.
• When all the update processes are complete, restart your system.

Fix 2. Install or repair Microsoft Visual C++ Redistributable

Many Windows applications rely on Microsoft Visual C++ Redistributable packages to function. If these packages are missing or corrupted, applications may fail to start correctly. Repairing or reinstalling them can restore the required dependencies.

• Right-click on Start and pick Apps & Features or Installed apps.
• Scroll down to find Microsoft Visual C++ Redistributables.
• Click each version or click three dots, select Modify, and choose Repair.
• If repairing does not work, uninstall the packages and download the latest versions from the official Microsoft website.
• Install the downloaded files and restart the computer.

Fix 3. Reinstall the affected application

If the error occurs with a specific program, it may be due to corrupted files or a faulty installation. Reinstalling the application ensures that all necessary components are correctly installed and replaces any missing or damaged files.

• Type Control Panel in Windows search and press Enter.
• Select Uninstall a program under Programs section.
• Scroll down and find the app you are having the problem with.
• Right-click on it and select Uninstall.
• Follow on-screen instructions to remove the app, then reboot your device.
• Re-download the app and install it again.

Fix 4. Run SFC and DISM scans

Corrupted system files can prevent applications from accessing essential Windows components. Running the system file checker and deployment imaging tool can repair missing or damaged system files automatically.

• Type cmd in Windows search.
• Right-click on Command Prompt and pick Run as administrator.
• User Account Control pop-up will ask to confirm, click Yes.
• Type in the following command and press Enter:
  sfc /scannow
• When done, run the following commands as well:
  dism /online /cleanup-image /scanhealth
  dism /online /cleanup-image /checkhealth
  dism /online /cleanup-image /restorehealth
  (Note: if you get an error executing this last command, add /Source:C:\RepairSource\Windows /LimitAccess to it and try again).
• Restart your computer.

Fix 5. Scan your system for malware

Malware infections can modify system files, interfere with application dependencies, and cause errors like 0xc0150002. Running a full system scan helps detect and remove malicious software that might be affecting application functionality.

You can use a trusted third-party app, Microsoft Safety Scanner or the built-in Microsoft Defender:

• Type Windows Security in the Windows search bar and hit Enter.
• Select Virus & threat protection.
• Pick Scan options.
• Choose Microsoft Defender Offline scan and click Scan now.
• Your computer will immediately reboot and begin a deep scan.

Fix 6. Perform a Clean Boot

Conflicts between background services and third-party software can prevent applications from launching. A clean boot starts Windows with minimal services and drivers, helping to identify conflicts.

• Type msconfig in the Windows search box and press Enter.
• Pick the Services tab.
• Mark Hide all Microsoft services and select Disable all.
• Select the Startup tab and click Open Task Manager.
• In the Task Manager, right-click on each of the items and select Disable, then close the Task Manager.
• Go to the Boot tab, mark the Safe Boot option, then click Apply and OK.
• On the System Configuration window, click OK.
• If the problem is gone, it means that the software is causing this. Disable each of the entries (or do that in groups) and reboot the system in normal mode; i.e., use the method of elimination.
