Issue: Unable to open debugger in AX2012R2 and user having admin rights as well.
Error: The X++ debugger works only for users who are in the ‘Microsoft Dynamics AX Debugging User’ local group of windows. Get added to the group, and then login again to windows.
Solution: In my case issue got resolved after running AX application with ‘Run as administrator’.
Steps: Press shift and right click on AX shortcut icon and click on Run as administrator.
