We are now happily running TTR on Linux. It is unofficial and they expressly forbid me from distributing it, which I won't so don't ask. I can understand their reluctance to package and support a Linux product. I hope that changes at some point. For now, I am just grateful that they were willing to share their unofficial package to make a few of their loyal customers happy.
why would they NOT make it available ? DOW has some really strange business practices that i will never understand.
