If you're facing file access issues with Connexion client 3.x even after reinstalling, it's possible that not all components were completely uninstalled prior to the reinstallation. To address this, follow the steps below for a comprehensive uninstallation and reinstallation process:
Note: These steps are applicable exclusively to Connexion client 3.x.
Uninstallation and Reinstallation Steps
1. Open the "Programs & Features" section on your computer.
2. Uninstall "OCLC Connexion client 3.x."
3. To ensure the complete removal of components from memory, reboot your computer.
4. If present, uninstall the "OCLC Connexion ComService."
