New User Install gets Error Mac OSX High Sierra

[OogieM]

Brand new user. Downloaded the Normal Users Mac version. UnZipped and tried to run web2py.app get this error with no other useful information. 

System is 10.13.6 High Sierra on an older iMac.

Never got the window to select a password or get started. I did verify that no other versions of web2py were present on the system.

Tried deleting everything and redownloaded it just in case but got the same error. 

Looked at Console but nothing listed web2py as a problem but I'm not skilled in reading console messages.

Suggestions as to what to try next.?
