Self-signed to symbian signed

[jascco]

Hi all,

I'm having following problem. We have developed app and used self-signing now we are going for Symbian Signed.

My problem is how-to update self-signed app with Symbian Signed.
As far as I know I cannot update it straight as UID:s aren't same.

So can I uninstall old application automatically and then install my signed app?

Other problem is that I need some user made files from old application to be copied to new application. How can this be sone while installing?

thanks Jascco

Hi,
You should unistall your old application manualy
because you probably would use another UID

1. step go to www.symbainsigned.com and register an account
2. get a UID from protected range
3. get a Publisher ID certicficate from TrustCenter (use manual from symbainsigned site)
for Express Signed you need to prepare zip archive (It contains sis file signed with Publisher ID , pkg file and txt (readme) file)
It is online procedure so if you have prepeared all of this
you get signed file in few minutes


Also I should notice you that it costs (200$ for publisher ID certificate and 20$ per evry singing) and you can'nt resign application

good luck!

Please note that the SDK Plug-in API includes one API that can be used to uninstall the self-signed version.

Some things to note:
The uninstaller requires Trusted UI capability to use
In addition to renaming your uid, you will also need to rename all your dll's and executables (remembering of course to build the exe to reference the new dll's and not the old ones)
Depending on where the data files are you may or may not be able to get to them - if they are in the private data cage then you will not be able to get them.

To my knowledge the TrustedUI is only needed if the (un)installation is to be done in the background (silent (un)install).

Thanks all.

I have solved all issues regarding how-to make my application so ready that I can Express Sign it (aqquiring id's, changing uid's etc and testing).

Now I'm trying to make uninstaller by using SDK Plug-in API's. I hope it goes fine wiht SDK Plug-in API.

Hi again,

OK, I have made some progress. I created .exe file which handles un-installation of my self-signed version. Then I run this file during installation of my signed version.

But, installer cannot un-install old version during installation because installer is already running.
What can I do now, can run un-installer after install?

Here's my code for uninstaller, if it helps someone else

LOCAL_C void doExampleL()
{
	SwiUI::RSWInstLauncher iInstall;
	RApaLsSession apa;
	apa.Connect();
	TInt status = apa.GetAllApps();
	TBool appFound = EFalse;
	if (status == KErrNone)
	{
		TApaAppInfo aInfo;
		while (status == KErrNone)
		{
			status = apa.GetNextApp(aInfo);
			if (status == KErrNone)
			{
				TUid oldone;
				oldone.iUid =  KmyUID;
				if (aInfo.iUid.iUid == oldone.iUid)
				{
					
					SwiUI::RSWInstLauncher launcher;
					int error = launcher.Connect();
					error = launcher.Uninstall(aInfo.iUid,SwiUI::KSisxMimeType);
					launcher.Close();
					appFound = ETrue;
					break;
				}
			}
		}
	}
}

Ok my solution for now is to use following line in .pkg file
"\epoc32\release\gcce\urel\AppRemover.exe"- "!:\sys\bin\AppRemover.exe" ,FR,RI

And it runs during installation, but when it starts I use User::After() to stall it for a while so that installation is completed.

Works fine, but if someone can tell me how-to run un-installation during installation I would be happy

Search for RI in the SDK Help, and check what the other possibilities are.
