It looks like yet another bug on the 2019 TT.
According to the instructions received with the CD it should allow activation on 5 different computers, regardless of what tax data file you feed to it.
Yes I copy my tax data file from one computer to another, but if I want to make a test tax return to calculate estimate tax for next year, it should let me do whatever I need to.
This whole activation system is just stupid, it should just keep track of the S/N of the computer and allow activation on 5 different machines as it says on the instructions.
