Q: What are OEM products?

A: OEM, or Original Equipment Manufacturer, products are different from retail versions in both licensing and packaging. OEM software is full version software and will not act as an upgrade. OEM does not come in a retail box, is always licensed for one computer, is not transferable and does not come with free manufacturer technical support. OEM products have the license on the CD. No paper license is required for OEM products. OEM products usually consist of a CD, COA (Certificate of Authenticity), and a quick start guide. The full manual is accessible on the CD itself.

Q: Is your software Used?
A: All software is 100% brand new.

Q: Is your software authentic?
A: Yes, all our software is 100% authentic.

Q: Do I need to buy a licensed copy for every computer I own?
A: Yes, you are required to buy a license for every computer you own. Each individual software product has thier own licence.

Q: What are Licenses, COA or EULAs?
A: Licenses, or End User License Agreements (EULA), give a customer the right to install and use that program on a machine. Some OEM products come with (COA)Certificate of Authenticity which confirms that the product was legitimately manufactured. Some businesses prefer this because it allows them to place a sticker to visually identify a system with specific software.

Q: What are Retail products?
A: Retail Products are the same products you purchase at local software stores. It is packaged for retail sale and include retail box, cd(s), manual, paper license agreement, and registration card. Any customer qualifies for retail products.

Q: What are Academic products?
A: Academic products are for use by students, faculty, or staff of an educational facility. These products are identical to the standard (non-academic) versions except the license is labeled "Academic". Customers should determine their eligibility before purchasing Academic products.

Q: What does CAL stand for?
A: Client Access License. These allow the right for a computer to have access to the server, which is different than an operating system or workstation license which grants you the right to have an operating system running on your system.

Q: What does no media mean?
A: No CD or floppy disks are included. An example may be a licence pak such as a 500 user server licence.
