* Operating systems no longer supported by Microsoft are not targeted platforms for WinDaq software. While such operating systems to the best of our knowledge still support WinDaq software, unpredictable problems may occur that will not be considered by DATAQ Instruments to be a failure of the software to perform. Further, no hardware products released after an operating system is discontinued by Microsoft will support the discontinued operating system. If you have any questions regarding compatibility of specific DATAQ Instruments hardware and operating systems, please contact DATAQ Instruments, Inc sales at for clarification.
