Before you can install your Adobe CS4 suite you'll need to find the serial number that came with the programs. Adobe CS4 requires that you enter a unique serial number before using it.
If you've lost your serial number, there may be a way to find it as long as Adobe CS4 is still installed. You might be able to find your Adobe CS4 serial number if you've uninstalled the suite but only if the serial number information was left in the Windows Registry.
The Adobe CS4 serial number is actually more of a product key than a serial number but the terms are often used interchangeably.
Using a free product key finder program would certainly be the easiest way to find your unique Adobe CS4 serial number. Product key finder programs automatically search your computer for the product keys and serial numbers that your software programs store in the registry.
If you knew the exact registry key that stored your Adobe CS4 serial number you could find it manually but that information is usually hard to come by.
Most product key finder programs are designed to find serial numbers and product keys for operating systems like Windows XP or Windows Vista but some of them find serial numbers for several other programs too - programs like those in the Adobe CS4 suite.
I've reviewed several product key finders but I haven't been able to personally confirm if any of them will find your Adobe CS4 serial number. The best key finder programs are quick downloads and completely free so feel free to try them all until you find one that will find your Adobe CS4 serial.
Here are two of the more popular programs that find serial numbers and product keys:
If neither of the above programs find your Adobe CS4 serial number, give some of the other key finder programs a try from my Free Product Keyfinder Programs list. Be sure to let me know what programs did or did not find your Adobe CS4 serial so I can keep this page updated.
Important: You may have come across Adobe CS4 keygen programs or other kinds of Adobe CS4 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 suite is by using a valid Adobe CS4 serial number obtained through a legal purchase of the software from Adobe or an authorized retailer.
Each Adobe Creative Suite 4 edition will likely have a unique serial number. Some of the Adobe CS4 suites included Design Premium, Design Standard, Web Premium, Web Standard, Production Premium, and Master Collection. These CS4 suites contain different combinations of the various Adobe CS4 programs.
