Unable to install SmartSDR_v3.2.39 on Windows 10 laptop

I uninstalled v3.1.12 before starting the install process and performed a reboot. After downloading v3.2.39, accepting default installation options, when I click the final install button I see a quick flash of a CMD window in the background and the install quits. No install directories created, no programs installed. Plenty of free space and ran full AV scan with nothing found.

I've tried running as Administrator but same results. I've downloaded and installed v3.2.39 with no issues on 2 other computers. Can't figure out my issue on this laptop.

Any ideas?

    Good Evening:

    Did you follow this process when you uninstalled SmartSDR?

    Hi Jim, you might want to submit a helpdesk ticket. The Flex folks have seen a lot of install anomalies, and can probably get you going again pretty quickly.

    From Mike’s email to me

    Worked for me Same symptoms


    2) We have had a few reports from individuals who needed to run the installer in “Compatibility Mode.”

    Here is a procedure that worked for other customers who have had this issue:

    Right-Click on the installer file.

    Click on "Troubleshoot Compatibility"

    Click on "Try Recommended Settings"

    and follow the directions.

    Thanks for the Compatibility suggestion. That worked!

    Well I spoke too soon. Everything installed but when I connect via SmartLink I have an issue with DAX drivers. I've followed the information from here:

    But still encountering DAX driver error.

    No SmartSDR works if you shut off auto run DAX.

    That was also part of my problem. Since you are also having the DAX problem contact Tim.

    He Teamviewed my computer and fixed the corrupted DAX.

    Your almost there.
