The same API works all the time, just make sure that the SIS file you are attempting to install is properly signed.

hi ltomuta, my sis file that i am attempting to install is signed and working properly and running on feature pack 3 and 5 devices .
my problem is only on symbian^3 devices
i read a comment on symbian forum by wizard_hu_ for the same prob in symbian saying that "The same API-s exists, just there is no plug-in pack (yet?) "and about "copy the missing files into the SDK. "
you can check the discussion here

where i posted there before posting here.
thank you for any help

This has nothing to do with the existence of the API. If you have built your application then you have had [a version of] the API and the expectation is that it should work (within the limits of binary compatibility, of course).

Now, there's only one thing that you can do, and that is to debug your application and see what works and what doesn't, and where the error may be coming from. The error code or, in case your application crashes, the panic code gives you much of the info you need to solve the problem.

hi again;
i tried to debug my application when using symbian ^3 devices, no panic code is there, the app is always entering the case XQInstaller::UnknownError: and giving me the message Box Unkown error ,error in installation
so i didnt figure out the origin of my error since the error is unkonwn!!!
any advice what should i do here to solve that problem? i tried it on N8 and E7 with the same error case
Thank you
