In Windows XP ( and ONLY XP,) Microsoft have decided that it would be easier to have a single MAC address for all devices in your computer if you choose to do that, but this causes problems. This shows itself when you do your 'ipconfig /all' command and the description line for the adapter is "MAC Bridge Miniport." To fix this you need to unbridge your ethernet adapter (don't worry if that sounds very technical, the simple instructions are below so just follow them).

When starting SMAC, why am I prompted to load a Microsoft Office CD?

SMAC does not actually use Microsoft Office. However, SMAC does use the Microsoft Common Control component (Mscomctl.ocx) for certain dialog features. This is a standard Microsoft file that is frequently upgraded by applications including Microsoft Office. This is a known Office 2000 issue that has several causes. One cause is that Office was installed on Windows 2000 under a non-administrative context. The fact is that when Office installed the Mscomctl.ocx file, it did not properly register the file with Windows. Therefore, when launching any third party applications that reference the control, Windows will either prompt for the Office CD to complete the installation or generate an error.

The solution is to load the Office CD when prompted and allow Office to complete the installation. If you receive a 1706 error instead of the CD prompt, you must login with an administrator account, start the affected application and load the Office CD when prompted.

Why do I get the message "SMAC has determined that you have insufficient registry access...?"

For Windows 2000, XP, 2003: In order to use SMAC, you MUST login with an administrator level user account. You MUST have READ and WRITE access to the registry of your Windows 2000, XP, 2003, and VISTA system.
