what are the disadvantages of using ClickOnce Deployment in .Net?

Question

Can someone tell me some disadvantages of ClickOnce deployment with respect to other means of deployment?

Answer 1

ClickOnce also deploys your application as other setup projects, but you'll miss installer UI customisation.

Answer 2

One significant disadvantage is that ClickOnce only applies to the user who installs it. It is not shared with other users. This may or may not be a problem for your specific use case.

This page lists several differences between ClickOnce and standard installs.

Answer 3

The registration of com dlls is a little bit tricky if you want to install them parallel with other versions of the com dll. (works with Isolated com registration).

You can't refer to specified paths/folders on the client machine, for example config files
