ClickOnce - Client Requirements

Question

Hello,

I am currently working with some users that do not have the .NET Framework installed. I have a ClickOnce application I am attempting to deploy. This has lead me to arrive at two questions:

1. What is the minimum version of the .NET Framework required on these users machines? I have heard .NET 2.0 and .NET 3.5.
2. If a user has .NET 2.0 do they need admin privileges to upgrade to .NET 3.5?

Thank you.

Answer 1

The framework required would depend on the application you are deploying and which framework it is targeting. If you are not sure, I believe the setting in VS 2008 is on the project properties, Compile tab, Advanced button.

Not sure about the admin requirements, so I won't guess.

Answer 2

As bare minimum, you will need .NET 2.0 on your machine (otherwise the .application file will not be recognized) and I do not think you need admin rights for .NET 3.5.

Hope this helps.

Contrary to the currently accepted answer, you do not need to have the .NET Framework installed in order to use ClickOnce. You're not supposed to use the .application file directly - doing so bypasses the prerequisite check. ClickOnce marks the appropriate version of the .NET Framework as a prerequisite and installs it as such when you use the setup.exe.

However, the user does require privileges to "install" if they will be installing the .NET Framework via ClickOnce. Another interesting point to note is that the user does not require "install" privileges to install ClickOnce apps if they already have the .NET Framework.
