> [Here](https://1drv.ms/u/s!AsTX3WCH_RLChkcEP2wP-RhKL8a0) is a link to test software for Win platform. There is a Visual C redistributable package included as well (just in case). Connect LimeSDR-Mini board and push Start test button to start testing. Log file will be created after test is complete. Share the log file, please. Regarding LimeSuiteGUI - yes, you have to push Default button after you connect to the board in order to set configuration for LimeSDR-Mini board.
