Configuration file or directory is not writable while installing

[n0timportant]

Hello, I'm trying to install Joomla on my localhost wamp server and it keeps to show me a message:

Your configuration file or directory is not writable or there was a problem creating the configuration file. You will have to upload the following code by hand. Click in the text area to highlight all of the code and then paste into a new text file. Name this file 'configuration.php' and upload it to your site root folder.

What can I do?

You have to give the web server permission to write to the folder.

Thank you for your reply, I gave all folders 775 permission and it works now

"775" is not correct.....but is that a typo? 755 (not 775) for files and 644 for folders are the correct settings,

775 can be correct for the configuration in use. It depends on how the security is set up and how the webserver is configured.

With 755 the webserver must run the php scripts as the owner of the webspace.

You were right, I changed rights to 755 for folders and it still works, thanks for your help!
