I recently faced a problem regarding an non-standalone (PA) symbian signed application. I found that after using V1 of my app, if I try to install V2 "security reasons" prevent it from being installed and I cannot use it. I realized the UID stayed the same across version so that may be a problem.
So except by having each version of an app bear a specific UID, is there a clean and safe way to instruct the system to either properly remove a PA before a new one is installed ? Or telling the system that this particular PA is actually an upgrade of a previously used one ?
