What if the shared library exists, but the error still occurs? What could be the problem?

If the file exists, the issue might be a version mismatch. The program might be looking for a specific version of the library (e.g., `libexample.so.1.2.3`), but only a different version (e.g., `libexample.so.1.2.4`) is installed. Also, check file permissions – the library needs to be readable by the user running the program. Finally, ensure the library isn't corrupted; try reinstalling it.
