How to: Specify an Installation URL
When publishing a ClickOnce application, the location where users go to download and install the application is not necessarily the location where you initially publish the application. For example, in some organizations a developer might publish an application to a staging server, and then an administrator would move the application to a Web server.
In this case, you can use the Installation URL property to specify the Web server where users will go to download the application. This is necessary so that the application manifest knows where to look for updates.
The Installation URL property can be set on the Publish page of the Project Designer.
Note The Installation URL property can also be set using the Publish wizard. For more information, see.
