quite few time for me in this situation changing the date worked magically, just change the date to couple of year back and install the application and once done change the date again.
If you google this I think you will get many posts regarding this thats how I found this technique.
But I am not hundred percent sure if this will work in case of installing Qt

Symbian (from Symbian 9) comes with a platform security modul to allow installing only trusted content. This means that the sis file should be certified (symbian signed) and this certification has an expiration date. This is the reason that in most cases changing the date solves the issue. Anyhow it is quite strange that on these relative new packages the certification expired.

Strange behavior, I have tested it on my Nokia N8 without changing anything it worked flawlessly, although I got back to Qt 4.6 because of production application which I am testing.

Yes, I am also sure that the certificate would not expire. It might be that the date and time on the device was wrong.

Yes I think I had same issue but I cannot remember exactly.

Can the author mark this topic as [SOLVED] it is easier to see if was solved and people learn by this?

If the thread is closed now. We won’t find whether the issue was with certificate date or the date on the device was wrong.

May be we should wait till David Chang confirms what the issue was. And then the admins can close this thread.

Maybe it means that if you post reply on that thread you will not receive points for it… :) No, I am just kidding. I am also interested what it exactly means and how it is governed (and it easily can happen that I have not read the posting rules thoroughly enough).

On a CLOSED thread no one can post comments anymore. This state can be set by forum admins. It’s usually done when the discussion becomes too off topic or things escalate in another way.

Marking a thread as SOLVED is just an addition to the thread’s topic. The original poster (or a forum moderator) can change this. It usually marks that a question is answered sufficiently. It does NOT mean that further discussions are prohibited. That would not be a good idea either: Although a problem is solved, discussion may bring up even better solutions.

Thanks Volker, as I said above this was not clear to me, as well.

You’re welcome. Sometimes it’s not obvious for the regulars that new users are a bit confused by the meanings of some terms. I’ve added a section with that explanation in the Forum Help [developer.qt.nokia.com] so that it’s easier to find in the future.
