You can open an application in Desktop in two ways:
- Open through file system
- Open in server
When you open in server it is logged as usual in the session log and so on. When you open through the file system the QlikView server is not involved and hence can not log anything. So if you want to log this you need to get some other data source. In Windows server there is a function called Object Access Auditing that I guess could be used.
