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.
