2. Click legacy administration link as circled in the image below
3. Under Maintenance in the middle column, select Settings 
4. On the Settings page, select UgandaEMR from the left hand side
5. Change the value of the RT Patient Identifier to true, then click the Save button 
6. Restart your computer and the new identifier will be enabled.
