Many times you will see software for sale that is listed as OEM , Academic, Upgrades, or Full Versions, all at different prices. This may lead to some confusion making you think that they are all different products. In reality they are all the same products, but are priced differently.
OEM stands for Original Equipment Manufacturer. Oem software is generally only sold by hardware manufacturers who include the OEM software as part of the total product. For example, when you purchase a new computer and it comes with Windows, it is the OEM version of Windows. Software wise there is no difference between the OEM copy and one you would buy from a store, but the manufacturers buy it in such bulk that they get huge discounts.
Academic and Not For Profit versions of software are software that is priced for a specific type of institution. Manufacturers generally sell their products at a steep discount if the buyer can be considered a educational institution or a non for profit institution.
Upgrade Versions is a way software companies have you continue to use their software or to switch to their software. These upgrade versions are usually the same as their Full Version counterparts, yet are at a significant discount. When they the Upgrades are installed on your computer, if they do not detect a piece of software that they feel is from a previous version or similar application, the upgrade will not work and it will direct you to buy the Full version. The upgrade is always cheaper than the Full Version, sometimes up to 50% cheaper.
Full Version software is exactly as you would think it would be. It contains the full software and can be installed on your computer regardless of whether or not you had a previous version or similar application installed. These versions are always the most expensive, and as there is generally always a way to get away with using an upgrade, you should never purchase a Full version of the software unless it is absolutely necessary.
Hope this clears up the different versions of software that you can find available.
