Localhost installation fails

Hello,

I am using xampp and cannot get the system installed.

The files are located in the following folder: http://localhost/dev/invoiceplane
When i go to setup: localhost/dev/invoiceplane/index.php/setup
it redirects me to: http://localhostc/xampp/htdocs/dev/invoiceplane/index.php/setup/language

My .htaccess looks like this:
RewriteEngine On
RewriteBase /dev/invoiceplane
RewriteRule ^index.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]

Please help

Please take a look at this: Wrong URL in 1.4.7

Thank you…that got it sorted
