I have installed UniServer3.2a on a WinMe system. Clicking Start.bat generates the following mesage: Error!!! One of the instances of Apache server is started. Use stop.bat Using Norton's Utilities I can monitor the active processes. There is no Apache running on the system. I verified that starting MySQL shows up in the active process window. From your other help messages, I checked that there are no php.ini or libmysql.dll files on system other than in Uniserver folders and emptied all temporary file folders. Finally, I did a search of the registry for Apache and Mysql and found no extraneous listings. The problem still exists.
