Ready to repurpose your QuickBooks installation CD as a fancy coaster for your favorite beverage?
You really don't need the CD any longer (unless you are still using a version of QuickBooks prior to 2006)
You can download the QuickBooks installation software directly from the QuickBooks support site - once you are there, just click on "Downloads and Updates", select your version and begin the process. As of this writing, you can still obtain versions as far back as 2006 from the support site.
SO THERE IS NO CONFUSION
It is essential that you have both the license number and the product number that came with your purchase of QuickBooks. It is those two numbers that are critical to the installation. So be sure to store those in one or more locations for easy reference. Without them, your installation (or reinstallation if that is the case) will not be successful.
Your best plan of action is to simply download the installation file from the support site and then burn it to a disc or store it anywhere you like for safekeeping. That way, in case Intuit changes their mind about making this information available, you'll still have a copy of it handy.
IF YOU DON'T HAVE THE LICENSE OR PRODUCT NUMBER...
If you find the need to reinstall your QuickBooks for any reason and don't have either of these numbers, your ONLY solution is to contact the folks at QuickBooks.
This is NOT something I can help you with...sorry.
