For what it is worth: I tried the new version of Hiren's Boot CD/USB, which is based on Windows 10 Preinstall-environment (aka Windows PE). I loaded it onto a USB, and added TechSuite to the same USB. When booting a few computers from the USB, it worked!!
By the way: I am no longer subscribed to TechSuite, and I completely expected to get a warning message saying so when running TechSuite. To my surprise, the procedures did seem to run. I don't know it this is an error in my account, a bug, or known behavior.
I don't run TechSuite any more at this time, I just wanted to see if it would error out on that computer. If it gave me errors about missing libraries or .net frameworks, etc., then I would've known to try something else.
The new Hiren's is completely free and only contains legal software, according to their homepage (whether we can trust them to make such an assertion, however, is up in the air I would suppose. I digress...). If you want a bootable USB tool to run TechSuite, you may try that.
It is bootable on both traditional BIOS and UEFI machines. I would point-out that it doesn't have a complete arsenal in the way of device drivers. Although it seems stable in general, it might not work completely on every system you try.
