Enable installation of "All" applications in Settings of the Application Manager. E-Series device come with "Signed only" as factory setting.

If ReadUserData is the only capability you use, it should be OK with self-signing. However you may depend on other capabilities you have not mentioned yet. Check them in the .mmp file(s).

Thanks a lot.

no, with "self signed" I can not install it on the real device, no more executing it. How can I check it in the .mmp file?

Thank you

Open the mmp file in an editor and check the line which mentions 'capability'. Perhaps you have put some capability in which self-signing is not sufficient.

You open it and your eyes at the same time...

Thank you for your reply

I have signed my SIS file successfully according to your hints, but I can't load it to my mobile telephone. A dialog "the application is due to a unbelievable provider not installed" takes place. I don't know why.

my mobile telephone is Nokia E65

Your translation of the error message is funny but also confusing. How about switching your phone to english at least during the install phase so that you can reproduce the exact error message?

See http://blogs.forum.nokia.com/index.p...7&articleId=93. To me at least is seems that you are facing the "Unable to install a protected application from an untrusted supplier".
