Hello Mark.I have same problem. Tomcat (version 9) installed and running. Increased the memory allocation in web.xml. Deployed enterprise war without problem. Installation did not start. Nothing happened. Via Tomcat manager UI, I stopped the war. Redeploy again. Same situation, Nothing happened.
Then I came across your post and downoaded the legacy UI module. But ran into a problem.
On P4 of your install guide, it said "Place the downloaded .omod file to ~/.OpenMRS/modules/".
Where is this openMRS main folder is?
I am not able to deploy openMRS from Tomcat manager. So nothing is setup. So I cannot find this folder.
