    Problem installing self-signed applications

    Hi everyone,

    I cannot install my applications on my cellphone anymore. I am using Carbide C++ 2.0, and I am self-signing my applications.

    Everything was working fine until this morning where my cellphone just refuses to install my applications. There is no capability in my applications. My N97 gives me the error: Expired certificate

    I tried playing around with the clock of the phone, but I still get certificate errors (when the cellphone clock is set before to what it should be, I get "certificate may not be yet valid", and if I set it later I get "expired certificate").

    I tried to reinstall the SDK and did a hard reset to the cellphone, but nothing changed. Please help me, I don't know what to do! Even the Helloworld application does not install!

    Maybe you should just re-do the certificate, so you would know the validity period.

    Thank you for your response. How can I re-do the certificate? I tried to remove my project folder in epoc32/BUILD but the problem remains.

    Re: Problem installing self-signed applications

    Thank you for the link. However the problem does not come from the phone itself, because the installation succeeds on another computer (which have the same date by the way).

    I tried to re-do the certificate, but that does not work.

    What I am doing now is making the certificate on the machine where the installation works, and signing the sis file using this certificate on the machine where I am having problems. That works.

    So I guess the problem comes from the certificate generation, but I have no clue how to solve this.

    The device does not accept time traveller certificates originating from the future. The clock (or even the date) on your problematic PC is set ahead of the clock of your device, that is the problem.
