What are some common errors or issues that may arise when adding a library like PhpPowerpoint to a PHP project on a Windows server?

One common issue when adding a library like PhpPowerpoint to a PHP project on a Windows server is the lack of proper file permissions.

Additionally, ensure that the paths to the library files are correctly specified in your PHP code.

// Example code to set file permissions for the library folder
