Installation completed but at the end of the installation a warning message box was displayed stating:
Error creating a new user. Please try it with the registration form at http://192.168.1.4/#registration.
I tried to login once via the browser on another computer with the backendless user I specified and it was successful.
NOTE: Installation was on a VMWare desktop workstation with Windows 10 Pro x64 installed with all security updates. Initially the RAM was set at 2GB.
For this and all other errors you reported, could you please zip up the log files from the following directories, upload them to google drive (or dropbox) and post the link here for each respective topic.
