You might have no access to that directory, are you logged in as an administrator? It might be a vista security issue. Or the file might be corrupted. I dont know, this has nothing to do with the guide, it has to do with your windows. Make sure these services (apache, mysql) are not running when you do such works.
Most probably you have an other copy of apache running (xampp? an older installation? a rooter? an other program that uses apache for his standalone administration console? something else?)... Stop that apache. Or you have IIS running! Stop IIS!
You might want to have a look at this.http://www.sitepoint.com/forums/showthread.php?t=409782&highlight=install+php+windowsHope it helps.
You should edit the apache configuration (httpd.conf) and set up your host. Apache is running so the guide is good and works.
A.Translator,In essence, 127.0.0.1 is localhost. Does the C:\Program Files\Apache Group\Apache2\conf\httpd.conf exist?Check to see if that exists and use notepad to edit it and see if localhost is defined.
C:\WINDOWS\system32\drivers\etc\hosts
Try a search on your system for the hosts file. Edit it to see if it too has 127.0.0.1 localhost on a line.Usually it is in Code: [Select]C:\WINDOWS\system32\drivers\etc\hostsDon't give up, you are almost there. Patience is a virtue.
