Welcome to the club! If it helps at all, be advised that the $150 disc version of TTax Business doesn't install on a Mac, either. I have not been able to find a substitute version for a Mac with TTax or its tax software competitors. Yesterday, I dragged out an old, slow worn-out PC and I am now trying to us it for TTax. If worst comes to worse then all the money you wasted is deductible as a business expense.
