How can Yii install a module that have the different directory

I want to install a moudle that called ‘ecshop’,which could stand along,and has the different directory achivement.It’s directory like this:

1166

my main config like this:

1165

I have tried many methods ,but just cann’t get the install file.

When I type the url:http://localhost/myYii/yii/teardrive/index.php/r=ecshop/install/install

,it have no notice.Just show the entry page. I want somebody who can tell me the truth.

Is ecshop a yii module ? Is it developed using yii framework ?

NO,It isn’t! The ecshop is another open source that do nothing with the yii framework! I just want to let other qpen system as a module in yii framework as one part of my project!
