Dynamics GP 2013 R2 - eOne Extender does not install - Keeps prompting to add new code, but never does

Cause
Extender thinks it's already installed, and will not install again

Resolution

• Edit the dynamics.set and remove the reference to extender
• decrement the number on the first line of the file by 1
• remove the line that says "Extender" and the number above it 3107 (do not leave an empty line)
• Look for the three lines at the bottom that refer to extender and any EXTUD files
• Delete the three lines (do not leave an empty line)
• Navigate to the Program Files\GP folder
• Delete all files named Extender, or EXTUD with any extension
• Run the Extender install
• Launch GP
• Include code
• It should install correctly
