Hi,

We arerunning a clickonce application that is set tobe only available online. The application works fine,until an upgrade is done on the servers.Theproblem is that, the clients are unable to run the application after the upgrade is performed.We found that deleting the'Local Settings/Apps/2.0' folder, then having the client run the application again from IIS works. Is there a way to get the application to workwithout having to delete the application folder after each deployment?

Any help will be greatly appreciated.

I am using C# in VS2008. Application is runningfrom twoweb servers load balanced, inwhich we deploy to one server than copy the deployed folder to the other server. Server OS is windows 2003.

The problem is that you are moving the deployment. The installation URL must match the location of the deployment. If you have the deployment on multiple servers, the user must use the same server repeatedly. The location of the deployment is part of the identity in the manifest, and if it changes, ClickOnce no longer recognizes it as the same application.

This is part of the ClickOnce application security, which keeps someone from hijacking your application and substituting files from their own location for yours.

What are you trying to do with the multiple servers? To move the deployment to the second server, you have to change hte installation URL in the manifest and re-sign it with Mage or MageUI.

Hello,

Thanks for your posting on MSDN forum.

>Application is runningfrom twoweb servers load balanced, inwhich we deploy to one server than copy the deployed folder to the other server. Server OS is windows 2003.

If you just copy the deployed folder to another server, that the reason why the clickonce application doesn't.As ClickOnce can provide automatic application updates. AClickOnce application periodically reads its deployment manifest file to see whether updates to the application are available. Since you just copy the deployed folder, the ClickOnce application might not be able to get there information.

If you want the ClickOnce deployment on different server, I recommend you publish the application to the different server With Visual Studio. Another choice is that you can try with MAGE or MAGEUI tool to manually deploy the application.
