Before you can install TuneUp Utilities you'll need to find the serial number that came with the software. TuneUp Utilities requires that you enter a unique serial number.
If you've lost your serial number, there is a way to find it as long as TuneUp Utilities is still installed. You might be able to find your TuneUp Utilities serial number if you've uninstalled the program but only if the serial number information was left in the Windows Registry.
The TuneUp Utilities serial number is actually more of a product key than a serial number but as with most software, the terms are usually used interchangeably.
A free product key finder program will automatically search your computer's registry for your TuneUp Utilities serial number and for product keys and serial numbers for your other software programs.
The product key finder program that I've confirmed will find your TuneUp Utilities serial number is Magical Jelly Bean Keyfinder. If it doesn't find your serial number, try one of the other key finder programs that I linked to above and then let me know it didn't work so I can keep this page updated.
Most product key finder programs are designed to find the product keys for operating systems like Windows XP or Windows Vista but some of them find product keys and serial numbers for several other programs too, including TuneUp Utilities.
Important: You may have come across TuneUp Utilities keygen programs or other kinds of TuneUp Utilities cracks but keep in mind that these are not legal ways of obtaining serial numbers or product keys. The only legal way of installing this program is by using a valid TuneUp Utilities serial number obtained through a legal purchase of the software.
