Silent Installation

[preethi]

Hi

I am searching for a possibility to update an application without involving the user. When i need to update a executable i normaly should use a .sis and install it via the installer. However, its impossible to run the installer in a silent mode.

I have gone through the SWInstaller in nokia wiki.It is working fine,but as it is not public api, i am in search of some other way.

If any one have any idea about this ,kindly let me know.

regards

I am afraid that there is another way. Even if it is a part of SDK plug-in API, you can still use it in your application. Is there any specific reason not to use SWInstaller API?

Basically you can not update the application by calling any API from your own application. The installer is run embedded thus it is killed when the installer itself cloes your applciation while uninstalling it.

So you need to eithr have some additional executable doing it, for example you could download two sis files, use the SWInstaller API to silenty install the "updater app", which would then wait untill you close your app, and uninstall it, and re-install with the new sis, then the updated application could uninstall the "updater app".. a bit tricky but not too difficult really..

Hi

Thank you for valuable suggestions.

I will go with SW installer API.

Reason for not using it was ,as they are not in public SDK,they are not tested in every device ,so thought we cannot on rely on that ,without testing on every device.

Thats ok ,it will be better if i go for SWinstalelr api only,as i could not get any other option.

SW Installer Launcher API is a part of plug-in pack for S60 3rd MR, S60 3rd FP1, S60 3rd FP2 and S60 5th Edition; so there should not be any real problem using it on different devices.

I have not seen any problem, but as said it is plug-in API, thus there is no guarantee on any compatibility.

hello
i test the silent Installation and it work fine , but how can i check server for new version ?

[symbianyucca]

What do you mean by that ?

Is it your own application and own server, so just make a logic to figure that out, and use for example HTTP for communicating with your server.

hi yucca
yes its my own server and app , i mean that : i dont't know the file name because i uploaded the new version with the name of version like "1.0.0" then i want to check when there's a new version on my server i must download it and install

[symbianyucca]

Could you do that check from the application that requires updating ?, then you could hardcode it before compiling, otherwise, you could add a file in public folders for example, so you could read the information from other processes.

yes i do that check from my application that requires update and download the new version but to install it i start another process to do the update and switch to my application again after installation finished
1- app1 ---- check for new version
2- app1 ---- download new version if it exists on my server
3- app1 ---- kill his process and start app2 process
4- app2 ---- start installing new version of app1
5- app2 ---- kill his process after installation complete and start app1 again
i do all of this procedures but i missing no 1 (check for new version )

what i think of is the process

1. you send your installed application version to server.
2. in your server you decide if you have a newer version or not.
3. your sends a response the decision to client.
4. then client can download .
