Thank you RM999.
That solution worked for me and I hope others read your post.
This has been one of the most frustrating installs I've ever had with Intuit TT, and I've been using this product since 2006.
Normally, you would simply input the license that you get from Amazon directly into TT when it asks for it.
However, it now appears that you need to be logged into your Intuit TT account, and in your 'downloads section', and input the license code that you receive from Amazon...and then it will activate.
Those instructions would've been helpful if they were on the Amazon site!🙄
At least that's what worked for me.
I'm all set and good to go.
Again, thank you!
