CF11 web server configuration utility. access denied.

I have installed CF11 on my windows 7 PC for development.

I have also installed Apache 2.2

When I try to run the server configuration utility I get the message:

C:\Program Files (x86)\Apache Group\Apache2.2\conf\httpd.conf.1 (Access denied)

Why is that ?

I tried to run the configuration utility as administrator, but I get the same result.

I think that running as administrator is useless because this is a java module, so it should be the java engine to be run as administrator...

But I could be wrong.

Please help me because I have to do some developments and I badly need to have a CF11 running here.

Thanks in advance for any help.
