How to repair a broken Measure

savecancel

I downloaded the "Add PSZ-HP to all zones" measures from BCL, it is showing a broken script kind of red icon besides it. When i try to add the measure it says "Failed to compute arguments for the measure" Unable to locate primary Ruby Script path. It also doesnot show in the measures window. But when i run the model it throws an error "Measure "Add PSZ-HP to all zones" is missing its measure.rb file, update this measure and try again.

I tried downloading it again from BCL, however not able to as it is greyed out i.e. not allowing me to re-download. Kindly suggest how to update the measure or solution to remove the error at runtime.
