I have the following problem. I created an application that needs to be Symbian signed because it needs some capabilities. This application needs a license file as well, which is bound to the IMEI of the phone. Since it is not possible to have each individual license file Symbian signed, I thought that I can selfsign the SIS file that contains the license. But if I try to install this SIS file, I get the following error message: "Unable to install a protected application from an untrusted supplier".

What can I do to solve this problem?

Cheers, Mario
