problem Installing .bar file on blackberry 10 by sideloading tool

I've developed a small game by using unity3d tool. Then i've created .bar file and its successfully done. For testing i've used sideloading tool to install the bar file to the device. But i'm not able done it. I'm getting error which is below

Can i get any suggestion/solution what exactly the problem? or any better way to install the app for testing on the device

have you tried to sideload with Sachesi?

Try doing the install by USB instead of over wifi if you can. This will at least rule out network issues.

Its succeed!!:). I've tried by USB connection and i build & run directly from unity3d. Its working.

Thanks for your suggestions.
