Googling reveals many technical details and framework/OS prerequisites, but it seems to be hard to find a source that lists the permissions that are required for installing and running a ClickOnce app.
This is especially interesting for delivering software to customers that work in large corporate networks with many security restrictions and centralized policies that define which version of what is installed etc. "Standard" users in these networks are still pretty much technically constrained in what they are allowed to do and what not (sadly, but that's another topic...).
What are the permissions that a user needs to start a ClickOnce app from the network?
Are there differences if the .NET Framework 3.5 is already installed? Does it work without an existing installation of the .NET Framework or an old version (e.g. 1.1/2.0) with the same permissions as above?
UPDATE:
To make it a little more specific, what permissions are required if the .NET Framework 3.5 is not installed yet?
What permissions are required if the .NET Framework 3.5 is present?
Anyway, thanks for all answers so far.
