SmartSDR v.3.5.9 Install Problems

Options

SmartSDR v3.5.9 will not install DAX and CAT on my Dell computer running Windows 11. I have tried the various workarounds with no success, including several suggestions made by very helpful Flex Tech Support folks. I have had the same problem trying to install it in Parallels on my Mac with M1 processor.

According to Flex Tech Support this issue has been logged as defect number: J8210 -- "DAX not installing on PCs and Surface devices if Core Isolation/Memory Integrity or Secure Boot is enabled, and will not install on some computers at all, even if Core Isolation/Memory integrity is disabled."

Has anyone heard when this issue will be resolved? I have deleted v3.5.9 and have re-installed v3.4.24 which runs successfully. I would like to upgrade but trying to install v3.5.9 has been a very time-consuming and frustrating experience.

    make sure core isolation memory is disabled, then right click the SmartSDR 3.5.9 installer and go to properties. You want to install in Windows 8 compatibility mode.

    I just went through that. I had to turn off Core Isolation.

    The other issue I had is that even with my FireWall turned off, it seems it wasn't fully off and there a few firewall rules were still in play.

    This didn't prevent SmartSDR installation, but DAX and CAT only did not see the radio. SmartSDR did.

    Thanks for the suggestions David and Mike. Turning off Core Isolation did not help. Given the trouble I have had, I am leery of some of the fixes. Is there any information on when the  defect number: J8210 -- "DAX not installing on PCs and Surface devices if Core Isolation/Memory Integrity or Secure Boot is enabled, and will not install on some computers at all, even if Core Isolation/Memory integrity is disabled." will be resolved so I can install this software normally without having to install it in Windows 8 compatibility mode?
