I have uploaded a new zip file to try to address the issues you have reported:
(a) FAILURE TO WRITE CONNECTIONS FOLDER
------ I removed the connections folder from the .zip file so it is created by the wizard entirely. That should allow it to be created with the correct permissions
(b) INCONSISTENCY BETWEEN ZIP FILE AND INSTALLER
------ I removed the version number from the installer entirely
(c) ADMINISTRATOR AS FIRST USER?
------- The super administrator is not created as a first user since it isn't required to be an email address. You can register that user separately.
(d) MISSING PORT NUMBER
-------- I added the port number
