Who is this article for?

Admins who want to understand the application versioning.

No special access or permissions are required.

You might notice that the version number shown in the application does not match the number shown in Add/Remove Programs. This article explains how the version is updated.

1. Version number
   • Application
   • Add/Remove Programs
2. ClickOnce package

1. Version number

Application

You can see the application version displayed in the bottom left corner of the screen. In this example, it's v5.4.0.11.

Add/Remove Programs

When viewing the entry for the application in Add/Remove Programs, you may see that the version number is different. In this example, it's 5.4.0.15.

This is because the version number shown in Add/Remove Programs is not the version of the application, it's the version of the ClickOnce package.

2. ClickOnce package

When the first ClickOnce package is copied to the server, it's given the same version number as the application. Each time the package is rebuilt, the version number is incremented.    

Below is a screenshot of the /Client folder from the application server from the example above.

We see that the ClickOnce package was created for v5.4.0.11. It has then been rebuilt four times since.

This is why the version shows as v5.4.0.11 in the application window, but the ClickOnce package version shows as 5.4.0.15 in Add/Remove Programs.
