I read from a previous help post on this topic which is marked as 'resolved': https://ttlc.intuit.com/turbotax-support/en-us/help-article/product-delivery/bought-cd-computer-cd-d....
In the post the answer said "But, keep in mind, you can't use both the CD and the download. You must use one or the other."
It's difficult for me to comprehend why these two installation methods are mutually exclusive. Like, why should installing from the downloaded installer somehow invalidate my purchased CD. I suspect the answer is wrong, could you verify?
I'd like to confirm that I can continue to use my CD to install to a 2nd computer (e.g. my brother's computer which has a CD drive) after I install Turbox on my 1st computer (without a CD drive) using the downloaded installer.
