Please let us know your OS and Intel VTune AmplifierXE versions.
Is the problem seen with your application only (not standard samples)?
If so, what kind of application do you analyze?
Was Amplifier installed and run by administrator user?
Also please provide Amplifier command line (there is "Get command line" button in GUI window).
English is preferred here so everyone can read the forum threads. I would suggest you to open an issue in premier.intel.com, as it may require some debugging and info exchange with you.
The command line can be get even from GUI, there is a button in the right bottom corner. This is just easy way to provide info about your analysis configuration.
Do you have same problem with other user-mode sampling analysises, like Hotspots?
Try EBS analysis (Lightweight hotspots, General Exploration), it may have no the issue so you can profile the application at least this way.
