Hi @Taylah Mitchell,
Welcome to Microsoft Q&A forum.
Regarding the issue - the Minecraft for Windows launch issue you reported, the error code 0x800700c1 typically occurs when a system file or a required dependency is corrupted or not recognized as a valid application. This problem can stem from some causes within the Windows environment or the Gaming Services infrastructure.
Please perform these troubleshooting steps below and keep me informed of the outcome:
- Repair and Reset Gaming Services:
- Go to Settings, then Apps, and select Installed Apps.
- Search for Gaming Services, click the three dots for Advanced options, and select Repair. If the error continues, please select Reset.
- Run the System File Checker:
- Open Terminal as an Administrator by right-clicking the Start button.
- Type
sfc /scannowand press Enter. This process identifies and repairs corrupted system files that may be blocking the game launch.
- Reinstall Gaming Services:
- Open Terminal as an Administrator.
- Run the command to remove the Gaming Services package from your system. After this is complete, search for Gaming Services in the Microsoft Store to download and install a fresh copy of the application.
Kindly update the outcome of these steps to let me further check if the problem persists. I will be available to investigate additional solutions if these do not resolve the issue.
