When adding a License Code during a LabTutor Server / LabAuthor Installation, why does the license fail to add, returning me back to the home screen?

When running the LabTutor Teaching Suite Installer, license codes can sometimes not be accepted (though no error is displayed). This is often caused by permissions issues on the target machine (primarily restrictions on the User Account). To resolve this issue, follow these steps:
- If using a standard User Account, switch to an Administrator Account (or ask your Computing Services Team to grant you one if not available)
- If the License code is still not accepted, run the Installer as an Administrator. To do this right click the installer and select Run as Administrator
