Hi,

I go on the 1st page: Step 1: End User License Agreement

And I accept the license agreement and when I click on Continue I receive error:

HTTP Error 500.0 - Internal Server Error
C:\Program Files (x86)\Parallels\Plesk\Additional\PleskPHP5\php-cgi.exe - The FastCGI process exited unexpectedly

Requested URL http://localhost:80/plesk-billing/admin/install/index2.php?proceed=1
Physical Path C:\inetpub\vhosts\default\htdocs\plesk-billing\admin\install\index2.php

Somebody please help urgent.

Thanks

Wasim
