I really need your help. I am about to publish a Symbian 9.3 application. The application is intended to be available by WAP and it will work 6 months (counter is implemented inside the application). The sis file is published with x-epoc/x-sisx-app MIME type.
However, I find a problem that after browsing to URL of the application, the application is downloaded to C:/Data/downloads or E:/Data/downloads and then installed. After installation, the installation sis file remains in one of these directories. It is visible from file manager and any user can reinstall the application so that counter will be reset. The user can even copy the sis file to the computer by Nokia PC Suite and install on another phone. Is it possible to delete sis file after installation or how else should I publish the application?
