Do whatever it takes not to start the item rather remove your modem from your desktop/compact PC. Right tap on the micromx modem image then pick Properties >Compatiblity then tick the caseRun this framework in compatiblity mode for: pick Windows XP(Administration Pack 2). By then tap on okay. Shortly replug your modem.
