Hi Olajide, Thanks for that, but I've already checked all of those and the answers are: Server_start.bat : No Error displayed. No other PHP, Mysql or Apache on the system, I don't have the firewall turned on as I'm not connected to a network at this time. Anti-Virus turned off for the same reason, and port 80 is not blocked. As regards the subst, for W. When I run the bat file to start uniform server, the W drive is created but the problem is between the W drive being created and the apache starting and the browser starting, the W drive dissapears. It is the cause of the drive removal that I can't find, I think If I could get the W drive to remain, I think all the other problems would resolve themselves.
