This problem is still there for the 2021 return. I had the exact problem with the 2021 version.
I have read the poster here. So many users were strugling to resolve this problem. But currently, what I see is that the method to resolve it is to call Turbotax, spending one to a couple of hours, and get a new license key. Some users were even not lucky enough to get a new license code.
Here is a simple way to resolve it. Find a computer with DVD drive, copy the file to a USB drive, install the software using the USB drive, activate the software using the license code. I have successfully installed the software in my second computer.
Alternatively, you can upload the DVD content onto a cloud drive. Then download from the cloud drive to your laptop computer and install it. I have test this way but I can't think of any reason that it can't work.
