I am trying to install a Lexmark 3550 driver on Windows 7 64 bits.
This is a Wi-Fi and USB printer
I found the correct driver on the manufacturer website, and the install procedure does not show ant error, but at the end the driver is not installed.
The same driver works on Windows 7 32bits.
The Microsoft tech site and the Lexmark site say the driver is ok for Windows 7 64bit.
How can I fund out what's is going wrong with the install ?
Is there a way to manually add this printer.
