I have the evaluation version of ArcMap 10.3 and it is working well. However, I was trying to run the associated ArcGIS Pro 1.4 but it won't allow me in. It keeps asking me for my ESRI account details and whenever I put it, it pops out an error notification that I cannot use it as an individual. Please, I need assistance on this.
I've just installed ArcMap & ArcGIS Pro trials. These two links will give you some background info:
You should have been prompted to create a new ESRI account with your trial. Using these account details, log into My ESRI and authorise access to ArcGIS Pro.
