I'm getting a 404 page when I don't have clean urls enabled after installation

Not able to reproduce it.

Can you please tell us how you installed commerce kickstart, which parameters on "Configure Site" & "Configure Store" pages ? And copy paste the error here.

line 467 of commerce_kickstart.install

But i tried without clean urls support and i was correctly redirected without 404 error.

I got this error too. I didn't have .htaccess file, so clean urls was unavailable.

Ok this error occur only if you are missing the drupal .htaccess file.

Just bring the .htaccess back and it will work as expected.

I get this same issue. It's due to the following setting in my apache config file, not the lack of a .htaccess file.

    AllowOverride none

Personally I think this needs to be addressed. While I can understand that most people have support for clean urls, it's not supported across the board, especially in development environments such as the default bitnami mamp installer.

You need the .htaccess to make it work. putting the AllowOverride option to None will disable the use of the .htaccess file.
From http://httpd.apache.org/docs/2.2/en/howto/htaccess.html

The use of .htaccess files can be disabled completely by setting the AllowOverride directive to none:
AllowOverride None

Drupal is designed to work with or without clean url's. If Commerce Kickstart has made a design decision that departs from Drupal's standards, such as not working without clean-urls, than we should have some sort of notification to the user. Otherwise Kickstart appears broken.

Have you ever seen a standard drupal installation working with the AllowOverride none setting ? Because it tells not to use the .htacess file, with the .htaccess file disabling clean urls works, kickstart didn't change anything to break that.

This could be eventually done by doing that : http://drupal.stackexchange.com/questions/12977/how-to-set-up-drupal-7-o...

I just tested on a default Drupal install. Works as expected. Furthermore, Kickstart works as expected once I manually change the path from http://example.com/admin/help/getting-started to http://example.com/?q=admin/help/getting-started.

One note though, the standard Drupal install doesn't automatically redirect me, but instead forces me to click a link to the home page. This may actually be an issue with drupal_goto(), or url() between the install process, and the operational site. Once I am on the site, the URL's are using the q parameter as they should.

Not sure this is super clean but it works for me.

Here's the gerrit commit https://code.drupalcommerce.org/#/c/599/

This solves the problem, however I still wonder why url() doesn't return the proper path.

Either way, it does solve the problem.
