Not able to install invoiceplane on localhost - Urgent

I am using apache WampServer Version 3.0.0 64bit.
Apache Version:2.4.17, PHP Version:5.6.16
mod_rewrite is enabled.
.htaccess file structure
RewriteEngine On
RewriteBase /invoiceplane
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule . index.php [L]

My files are in wamp64/www/invoiceplane directory. i have installed it on server successfully. On localhost when i access index file the welcome page shows setup option but when i click on setup url goes something like this. Not able to install it on localhost. Also no css included on localhost pages.

Please suggest me how could i solve my problem. Any help would be appriciated. Thank you

Please also take a look at this threads:

Its done

$config[‘base_url’] = (isset($SERVER[‘HTTPS’]) && $SERVER[‘HTTPS’] == ‘on’ ? ‘https://’ : ‘http://’) . ($SERVER[‘HTTPHOST’] ? $SERVER[‘HTTPHOST’] : $SERVER[‘SERVERNAME’]) . ‘/myfolder/’;

i have changed base url in config.php file.

Thank you
