"Package not signed error" while deploying to other system

Question

I have re-targeted my app to 8.1 and i submitted to store now for certification(and there was no package errors). 

And now when i try to deploy on other system, it gives me the error "Package is not signed or corrupted".

I googled and found that i have to sign it using signtool, but i didnt get it properly. 

Will the package error, affect my certification process?

what is the reason for this error?

How to sign my app?(detailed steps)

Also, can windows 8 users download 8.1 packages?

(because i have used NavigationCompleted() in 8.1 which is not supported in 8)

No windows 8 users can not use windows 8.1 packages unless they do the free upgrade to windows 8.1

Did you try and deploy the package created by visual studio or one that passed certification from the store?
