US-16x08 Settings panel on OS Mojave

[Alanmacdrums]

Hi
I have just acquired a US-16x08 interface but am unable to install Settings panel software on my 2017 iMac now running Mojave OS. I have used most up to date download available 2.10

Installation begins but stops with error encountered message and advises to contact manufacturer.

I contacted Tascam UK but they say there should be no problem.

I deleted all downloads as advised by Tascam UK and started again but settings panel still won't install.

Any suggestions
Thanks
