Setup Crashes with Unhandled Exception.

Running Windows 10, 64 bit

I downloaded a trial. But it won’t install as the setup.exe crashes, every time. There is an unhandled exception, Object reference not set.

I have uninstalled/attempted reinstall. No Joy.

I have tried installing without using setup by running each .exe for the various components but it is only partially successful. Enough for me to get my Trial clock ticking but not enough to actually do much.

I ran SetUp through Visual Studio 2017 debugger and sent the logfile to support over a week ago. I got a ticket number but nothing else has come back.

Does anyone have a workaround or can supply me we the correct sequence to manually install the various executables?

Thanks in advance for any help.
