NetIO-GUI System Requirements

The documentation says the OS requirement includes Windows 7 32-bit, and I have Microsoft's .NET Framework 3.5 installed. But I keep getting the error below.

NetIO-GUI works perfectly using two Windows 10 64-bit desktops, but I would like to use in the field with two older laptops that still have RJ45 sockets.

Error message begins:

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

** JIT Debugging **
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
<system.windows.forms jitdebugging="true">
</system.windows.forms></configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.
