Dear Fiat Lux,   Thank you for your, if cryptic, advising. I have my data (~12 years worth) backed up to a Thumb drive, but my 2011 edition, I think you know, is on CD's.  My computer-repair shop loaded all of my 'old Laptop' (Windows7) stored data and I write because I cant open QB on the new machine. Maybe this is all self evident.  So how do I 'reinstall' the QB2011 software, given no CD port ?   Thanks for your help        Chrisman
