Updating XAP withouth changing the app_id : sllauncher.exe

I have a Silverlight application installed Out-Of-Browser on multiple computers. Now I'd want to update the xap on those. I dont want to manually update every computer.

I know I can do it through sllauncher.exe but the problem is that my application is changing its app_id. I need to preserve it, is there any way to do that?

secondly, we need to specify a local file with the /install parameter. It does not seems to work if I specify the web url to my new xap, is that normal?

Thanks

I realized I can do it just by replacing the xap file directly in the local drive here :

"C:\Users\myuser\AppData\Local\Microsoft\Silverlight\OutOfBrowser\1111111111.appName\appName.xap"

But I am not sure it doesn't mess up anything by doing it that way. But it seems to work fine though.

For Silverlight OOB applications its always better (must) to use CheckAndDownloadUpdateAsync (to update) which will check and download if there is a new version of the XAP. You can check this everytime the user starts the application or before closing the application, or at regular intervals. No new app_id is created as its updating.

You can use sllauncher.exe to install the XAP (it doesn't update) creating a new app_id. And the /install:XAP file might be a local file or a shared file. It cannot be a web url.

You can give web url at /origin:Web Url. This will be useful when you want to update your application.

You don't need to use sllauncher to update your xap. All you need to do is call CheckAndDownloadUpdateAsync. It will check for a new version of the xap and if one is available it will download and update it for you.
