What are the differences between the Microsoft Windows Installer and the ClickOnce deployment?
Rating:
The following table displays the differences between the Microsoft Windows Installer and the ClickOnce deployment:
| Difficulty in application updates | The entire application needs to be reinstalled whenever an application is updated. | Application updates are provided automatically. Firstly, only the modified portion of an application is downloaded, and then the entire application is downloaded. Lastly, only the updated application is reinstalled from a new side-by-side folder. |
| Impact to a user's computer | Applications rely on shared components, resulting in versioning conflicts. | Each application is self-contained and does not interfere with other applications. |
| Security permissions | Requires administrative permissions and allows only limited user installation. | Allows non-administrative users to install applications. It also grants only Code Access Security permissions that are necessary for an application. |
