I have an HP Media center PC m7000n and can not completly install my Lexmark printer X74-X75. The HP computer shows missing driver lxbbdr5c.dll. This driver is on the Lexmark installation cd and I made a file in the HP computer with that driver in it. But the computer rejects it either way. There must be something about the HP computer not allowing Lexmark to install the driver. Can you help me with this problem? My computer is running Windows XP and SP3. email@example.com Thank You.
