That was until I realized that I was dealing with a ClickOnce application with the file format “.application”. This would be straightforward to remedy by using AppLocker’s own ability to create rules using the application as a reference file and then determine any disparity with the publisher value. With this and the customer’s scenario in mind, I quickly gathered that something with this specific application had been altered from the vendor’s part in a way that made the corresponding AppLocker Publisher-rule invalid suddenly. This in turn showed a notepad file summarizing that the application is being blocked by a group policy (translated from Swedish in the screenshot below). One of these applications happens to be delivered by an external vendor through a ClickOnce application on their website, meaning that the user is expected to click on a link in order to execute a program located on the vendor’s part.īefore this had been working flawlessly, however we were now met with an error message stating that the application could not be started.įortunately, a more distinct explanation would display when I clicked on Details… on the aforementioned message.

In this post however, I would like to share an isolated issue in which an already known application was suddenly blocked by an AppLocker Group Policy and how it being a ClickOnce executable required some creative thinking right on the spot.Īt one of our customers we have implemented the AppLocker technology to be based upon Publisher-exceptions alone, as each user only requires executing the same set of applications and not more in order to carry out their workload on their Windows 10 clients. In other words, it is a given implementation within an enterprise environment to further defend itself from the many and various threats that can stem from executing suspicious programs.

Thanks to it, administrators can restrict or allow end-users to run certain applications based on its publisher value, file path or even its unique file hash, all within an On-premise Domain-wide level.
