E71 Installation Problem

Hi all.

I am trying to install an app and get the error message: Unable to install a protected application from an untrusted supplier.

Now, I think this is because the app is unsigned. So, I downloaded SignSIS Gui and a 20 year cert and key from OPDA.

I then signed the sis file and tried to install it again but still get the same error message.

Oh, and software installation is set to ALL in app manager.

Can anyone help solve this?
