Hi,

The errors you are seeing (ucrtbase.dll, exception code 0xc000409, manifest conflict, contextual activation error) strongly point towards a deep conflict or corruption related to runtime libraries or application dependencies, which CapCut relies on.

You have already done some excellent troubleshooting with SFC, DISM, and updating Visual C++ redistributables. Since those haven't worked, let us explore other potential avenues:

1. Graphics Drivers:

• Problem: CapCut heavily relies on GPU acceleration. Driver conflicts or outdated/corrupted drivers are common causes for crashes, even if they seem unrelated initially (like ucrtbase.dll errors). Your laptop likely has both Intel integrated graphics (for the i5-11400H) and potentially a dedicated NVIDIA or AMD GPU.
• Action:
  • Go directly to the Intel and NVIDIA/AMD websites (whichever dedicated GPU you have). Do not rely solely on Windows Update or HP's support assistant for the latest drivers.
  • Download the latest specific drivers for your Intel integrated graphics and your dedicated GPU.
  • Consider performing a "clean installation" if the option is available during the driver setup (NVIDIA offers this). This removes old driver profiles that might be causing conflicts.
  • Restart your computer after updating drivers.

2. Clean Reinstallation of CapCut:

• Problem: The CapCut installation itself might be corrupted, or residual files from a previous attempt could be causing issues.
• Action:
  • Uninstall CapCut completely via Windows Settings (Apps > Installed apps).
  • Check the following folders for any remaining CapCut data and delete them if they exist (ensure hidden items are visible in File Explorer):
    • C:\Users\[YourUsername]\AppData\Local\CapCut
    • C:\Users\[YourUsername]\AppData\Roaming\CapCut
    • C:\Program Files\CapCut (or similar location if installed elsewhere)
  • Restart your computer.
  • Download a fresh copy of the CapCut installer directly from the official CapCut website.
  • Right-click the installer and select "Run as administrator".

3. Check .NET Framework:

• Problem: Similar to Visual C++, CapCut might rely on specific .NET Framework versions. Corruption here can cause launch failures.
• Action:
  • Ensure you have the latest recommended .NET Framework versions installed. Windows 11 usually manages this, but issues can occur.
  • You can try using the Microsoft .NET Framework Repair Tool (downloadable from Microsoft's website) to diagnose and fix potential issues.

4. Run in Compatibility Mode / As Administrator:

• Problem: Sometimes, applications have subtle incompatibilities with newer OS versions or require elevated permissions.
• Action:
  • Find the CapCut executable file (usually in C:\Program Files\CapCut or similar).
  • Right-click CapCut.exe -> Properties.
  • Go to the "Compatibility" tab.
  • Try checking "Run this program in compatibility mode for:" and select Windows 10 or Windows 8.
  • Also, try checking "Run this program as an administrator".
  • Apply the changes and try launching CapCut again. (Try combinations: just admin, just compatibility, both).

5. Security Software Interference:

• Problem: The buffer overflow error (0xc0000409) could potentially be flagged (incorrectly) by aggressive antivirus or anti-malware software as suspicious behavior.
• Action:
  • Temporarily disable your third-party antivirus/firewall software (use Windows Security/Defender in the meantime).
  • Try launching CapCut.
  • Important: Remember to re-enable your security software afterwards. If this does solve the problem, you'll need to add an exception for CapCut in your security software's settings.

6. Check Windows Event Viewer for More Details:

• Problem: Windows logs detailed information about application crashes which might offer more specific clues than the error codes you already have.
• Action:
  • Press Win + X and select "Event Viewer".
  • Navigate to "Windows Logs" > "Application".
  • Look for "Error" level events around the time you tried to launch CapCut. Source might be "Application Error" or similar.
  • Check the details pane for any mention of CapCut, ucrtbase.dll, or other faulting modules that might give more context.

7. Test with a Different User Account:

• Problem: User profile corruption can sometimes affect specific applications.
• Action:
  • Create a new local administrator account on your Windows 11 Pro.
  • Log in to the new account.
  • Install CapCut (or see if it's already available system-wide) and try launching it. If it works here, it points to an issue within your original user profile's settings or application data.

8. Try an Older Version of CapCut:

• Problem: It's possible the very latest version of CapCut has a bug specific to your hardware/software combination.
• Action: If you can find a legitimate source for a slightly older version of CapCut (be cautious about unofficial download sites), you could try installing that to see if it works.

9. Check for Windows Updates:

Ensure your Windows 11 system is fully updated, as sometimes installing the latest updates can resolve such issues. Installing update KB5011563 resolved similar crashes related to ucrtbase.dll.

10. Examine Environment Variables:

Conflicting environment variables can cause application crashes. If you have software like PostgreSQL installed, it might set certain environment variables that conflict with CapCut. Consider checking and adjusting your environment variables:

• Open the Environment Variables window:​

  • Press Win + X and select System.​

  • Click on Advanced system settings.​

  • In the System Properties window, click on the Environment Variables button.​

• Review and modify variables:​

  • In the Environment Variables window, check both User variables and System variables for any entries that might conflict with CapCut.​

  • For instance, if there's a variable like proj_lib (commonly associated with GIS software), consider removing or modifying it if it's causing conflicts. ​

11. Create a New User Profile:

Corrupted user profiles can lead to application issues. Creating a new user profile can help determine if this is the case:​

• Create a new user account:​

  • Press Win + I to open Settings.​

  • Navigate to Accounts > Family & other users.​

  • Under Other users, click Add account.​

  • Follow the prompts to create a new user account.​

• Test CapCut on the new account:​

  • Log into the new account.​

  • Install CapCut if it's not already installed.​

  • Launch CapCut and check if the issue persists.

12. Inspect for Software Conflicts:

Other installed software might be conflicting with CapCut. Consider the following steps:​

• Perform a clean boot:​

  • Press Win + R, type msconfig, and press Enter.​

  • In the System Configuration window, go to the Services tab.​

  • Check Hide all Microsoft services and then click Disable all.​

  • Go to the Startup tab and click Open Task Manager.​

  • In Task Manager, disable all startup items.​

  • Restart your computer.​

• Test CapCut:​

  • With minimal services and startup programs running, try launching CapCut.​

  • If it works, gradually re-enable services and startup items to identify the conflicting software.

Given the specific errors (ucrtbase.dll, 0xc0000409, manifest conflict), the most likely culprits are:

• Graphics driver conflicts/corruption. (Highly suspect for video software)
• Corrupted runtime libraries (despite trying to fix C++, .NET could also be involved, or the fix didn't fully take).
• A bug in the current CapCut version interacting poorly with your specific system setup (Win 11 23H2 + 11th Gen Intel + drivers).

Start with the graphics driver update/clean install and the clean reinstall of CapCut, as these are often effective for these types of issues. Good luck, and please report back if any of these steps help!
