Navigating to Robot installation folder <RPA Robot installation path>/uft, and launching UFT, the UFT can be accessed for the first time. A license error is seen if the UFT is accessed again. After running a flow, then the UFT can be accessed again.
This is an expected behavior.
When a flow starts, it will transfer the license to UFT. If UFT starts without running a flow, the UFT will try to get the UFT license as usual and throws license exception.
