[SOLVED] HTTP error 404 (problem with Apache service)

[HervE]

Hello,

I tried to upgrade from 2.4.9 to 3.0.6 on Windows.

After backuping my database and config files, I uninstalled 2.4.9.
Then I launched the Windows exe installer. The first part of the installation was OK.

But when launching web installer, URL http://localhost/otrs/installer.pl results in HTTP error 404.
(URL http://localhost/otrs/index.pl as well - of course.)

What do I have to do?

Regards,
HervE

Seen when I try to restart services:
"The Apache2.2 service is not started."

That could be the reason, couldn't it?

have a look in apache error log

I even cannot start Apache service manually.

have a look in apache error log

"C:\Program Files\OTRS\Apache\logs" is empty.
Which is obvious because I can see the 3 Windows application events:
"The Apache service named reported the following error:
>>> Unable to open logs . (
>>> no listening sockets available, shutting down .
>>> (OS 10013)Une tentative d’accès à un socket de manière interdite par ses autorisations d’accès a été tentée. : make_sock: could not bind to address 0.0.0.0:80 ."
(Sorry this last one is in French.)

What can I do?

I think I managed.
Seems SQL Server services used port 80. I stopped them, and then I could go on.
