  4. Download the missing dependencies from a reliable source and install them on your computer.

After installing the missing dependencies, check if the error is resolved.

Manually Register the DLL File

If the issue persists, you can try manually registering the problematic DLL file using the regsvr32 command. To do this, follow these steps:
