After you file

I doubt the actual .exe installation file is on that old drive....unless you actually copied the .exe installation file from the CD and onto the drive as a separate step.

 

The installation uses that .exe file to load a bunch of operational files onto your computer, from within the .exe file gibberish....just copying those offloaded files to your new setup won't get the software to work.....AND, you may well need the 16 digit installation code from off the physical CD itself to get it running anyhow.....and you don't have the CD anymore. 

(I make copies of my all TurboTax  installation codes in a .txt file....& print out each year, in case I need them in the future.)
