Do not delete system libraries outright. First, identify which application requires the library and secure your system.
System libraries like the Internet Explorer Active Interface Marshaling Library are often shared components. Deleting them can cause other programs, including Microsoft Office or system utilities, to crash or fail to open.
Check which software is set as the default to open G-code files (e.g., a text editor, Office application, or dedicated CNC software) by right-clicking the file and selecting 'Properties'.
Search the official support documentation of the identified software to see if it lists the Internet Explorer Active Interface Marshaling Library as a known conflict.
Press the Windows key, type 'Create a restore point' in the search bar, and select the matching result.
Click the 'Create...' button under the System Protection tab, name your restore point, and confirm to back up your registry and files before attempting any advanced troubleshooting.
