License Infromation is not saved after I close and open Visual Studio

If License Information is not saved between the instances of Visual Studio (e.g. ReSharper is asking for a License on every Visual Studio launch), please do the following:

1. Close all Visual Studio instances;
2. Uninstall ReSharper via Installer (For R# 8.x: via 'Control Panel | Add/Remove programs');
3. Remove the existed license information as described here;
4. Install ReSharper back;
5. Open single Visual Studio instance;
6. Enter your license information for ReSharper, when prompted. Press 'OK' button;
7. Gently close Visual Studio;
8. Open Visual Studio once again and check if the license information was saved;
