All, My company has a license for Exchange 2000 Enterprise. When we installed, the only installation media we had was not the Enterprise version of Exchange. Upon realizing this (we didn't know we had Enterprise licensed), we realized we needed to upgrade. We have been holding off until we received the correct media. Now comes the question. When I insert the Exchange 2000 Enterprise media into the CD-ROM drive, the AUTORUN kicks up, and I am prompted to install Exchange 2000 Enterprise. I choose this option, accept the terms and conditions, and then enter in the CD KEY. Upon entering the CD KEY, I am then forced into a component selection window. The top-level only has two options, "---" and "none". I am not prompted to upgrade, nor can I select sub components for upgrade. I can not continue as the "Back" button has been deactivated. Is there something special I have to do to install this version of Exchange? The current setup is Exchange 2000 (Standard), with SP2, and Windows 2000 Server, with SP2. On the machine I also have Symantec's AntiVirus for Microsoft Exchange 2.5. Any help would be greatly appreciated. -- Brandon Lockhart
