Component Virtuemart from Quickstartinstallation is error

Hi

I have installed myStore two times and clean up the database two time and still the problem is there.

In backend and administration panel there i click on components and virtuemart is something very strange and wrong.

when i click on one of the links to Configuration or Store or Products (all links) the link is wrong

The link is like this
/store/administrator/administrator/index.php?pshop_mode=admin&page=admin.show_cfg&option=com_virtuemart

As you can se is administrator two times????????

WHY??

Can someone help men out solve the problem??
