Does anyone know how I can uninstall an application programmatically, i.e. without using the phone or PC UI? I understand that the .sis file created on system\install holds info on the files to be removed at uninstall, but is there a command that is run with this .sis file as a parameter which will remove the application related to the .sis file?

Re: Uninstall API
Uninstalling an application from the phone means deleting some file and some directories/directory from file system. If you created the .sis you know what files you have to delete and from where. If not you can use a file explorer to find out what files where installed on your phone.

Re: Uninstall API
Thanks a lot... but my application knows only the name of the SIS file, which were installed on the phone. Nothing more. I want to do the same from my application as what would happened, if user would go to Application Manager and uninstall this application manually.

My question is: How Application Manager does uninstallation and if there is an API to do the same? Thanks for your help.

Re: Uninstall API
Do you know only the name of the sis or do you have also the sis?

Re: Uninstall API
If you have the name of the sis, you could try setting up a CApaCommandLine, using "z:\\system\\apps\\appinst\\appinst.app" as library.
Set the other fields appropiatedly, setting doc name (sis file name) and tail: cmdLine->SetTailEndL(_L("UNINSTALL")); and issue a RApaLsSession::StartApp()

Re: Uninstall API
Thanks a lot. I already found a way how to install an application from SIS file:

    CApaCommandLine* cmdLine = CApaCommandLine::NewLC();
    cmdLine->SetLibraryNameL(_L("z:\\System\\Apps\\AppInst\\Appinst.app"));
    cmdLine->SetDocumentNameL(_L("c:\\some_sis_file.SIS"));
    cmdLine->SetCommandL(EApaCommandRun);

    RApaLsSession ls;
    User::LeaveIfError(ls.Connect());
    CleanupClosePushL(ls);
    User::LeaveIfError( ls.StartApp(*cmdLine) );

    CleanupStack::PopAndDestroy(2); // cmdLine and ls

But when I changed the documentName to my uninstall SIS, I received an error (File corrupted).
    ...
    cmdLine->SetDocumentNameL(_L("c:\\System\\Install\\ListOfUIDs.SIS"));
    ...

It will try with the UNINSTALL option and I will let you know about the result.

Re: Uninstall API
... bad luck Sad

I tried following code and I have still "File corrupted!" error message. But I used _L8("UNINSTALL") instead of _L("UNINSTALL"), because "const TDesC8 &" is requested:

    CApaCommandLine* cmdLine = CApaCommandLine::NewLC();
    cmdLine->SetLibraryNameL(_L("z:\\System\\Apps\\AppInst\\Appinst.app"));
    cmdLine->SetDocumentNameL(_L("c:\\System\\Install\\ListOfUIDs.SIS"));
    cmdLine->SetTailEndL(_L8("UNINSTALL"));
    cmdLine->SetCommandL(EApaCommandRun);

    RApaLsSession ls;
    User::LeaveIfError(ls.Connect());
    CleanupClosePushL(ls);
    User::LeaveIfError( ls.StartApp(*cmdLine) );

    CleanupStack::PopAndDestroy(2); // cmdLine and ls

Any idea?

Re: Uninstall API
I have just found several things:

1) Someone already faced the same problem as me: "Unfortunatly this seem not to work for series60 version 2.0, because it has not worked on the 6600 for us. If I remember it correctly, the installer seem to try to install it fails with a corrupt file message."

I am playing with Nokia 6680, it means, Symbian 8.0 series 60 v2 FP2.

2) there is instapp.h file in SDK:

  // name of install app file
  _LIT(KInstallAppName,"Instapp.app");

  // NOTE: following must be given even length due to problem with
  // CApaCommandLine::NewL(fullCmdLine)) in EikDll::StartAppL()!
  // keywords at end of InstApp command line which tell it what to do
  _LIT8(KUninstallCommandLineTail,"UNINSTALLX");
  _LIT8(KInstallCommandLineTail,"INSTALLX");

  /**
  Constant shared between InstApp and InstCtrl
  @publishedPartner
  @released
  */
  enum TInstallMode {EUninstall,EInstall};

... still facing the same problem, it means, any idea more than welcome!

Re: Uninstall API
... again bad luck.

CInstallEngine is not supported in newer SDKs. Sad There is still insteng.lib library, but not insteng.h header file.
This header file was available in the Series60 1.2 SDK.

Do you think, that it could be still working, if I took the header file from version 1.2?

Does anyone have it? Did anyone try it?

I think, I have tried everything wat is available im my SDK... but nothing works. Sad

I think you can give a try....checking with the insteng.h from 1.2 sdk. You don't have anything to loose.....or?

Re: Uninstall API
I will try... just downloading SDK 1.2... my connection is not really fast...

Anyway... I was thinking, how the Application manager works.
I think, in first step, it just looks through all install directories to list all applications, which could be deleted (one application is equal to one reduced SIS file). In second step, when the user selects an application, it parses the SIS file and according to its content, it deletes files, etc.

I check the content of the reduced SIS file with WinHex editor and it really seems, that all information could be found in this file.

Is there any description of the SIS file and reduced SIS file structure?

Re: Uninstall API
It looks to me like AppInst should take "UNINSTALLX" as the tailing command rather than "UNINSTALL" ?

As for SIS the file format, details for it can be found at http://homepage.ntlworld.com/thouky/software/psifs/sis.html (thanks to Alexander Thoukydides).

Re: Uninstall API
As there has been no more replies, I assume you failed? If not, I would like to hear how you did it
