Hello all. Have a question I hope that someone out there can answer: Have installed MS Windows 2000 Professional on both my main desktop computer and my PII Compaq Armada M300 Laptop with no incident (using same product key). Have just recently received a PIII Compaq Armada which has Windows 98 as the O/S. Want to remove it and install Windows 2000 Professional instead. Here is where the problem arises. Attempts to install Win2K from my disc have failed with the folowing error message: Unable to copy MFC42.dll. Was able to find a fix, but additional attemps result in more dll (fontext, framedyn) messages and an acs (merlin) error message. I have been told that there is a licence restriction on installing Windows 2000 Pro on more than one computer. Is this correct? How do I go about rectifying this problem. Thanks to all for your comments/information.
