I received the error:
Operation could not be completed (error 0x00000704). The specified port is

Installing my multifunction printer/scanner/fax. Specifically Brother
MFC-440CN.
My OS is Windows 7, x64. I'm installing it as a network printer on the IP
address 192.168.1.69.
I received this error during installation, twice. I allowed the installation to
continue. After re-boot, I noticed my virtual fax printer was not there.
Everything else seemed to work fine.
I went to "Devices and Printers" and clicked "Add Printer".
I allowed the default LPT1, then I selected "Windows Update" to get
the latest goodies from MS.
I found the Fax printer for Brother PC-FAX v.2.1, and added it.
After that, I chose any printer and selected Printer Properties, then the tab
"Ports".
I clicked "Add Port", I selected standard TCPIP, and following thru, I
entered my port as:
192.168.1.69.
I opened the port for my Brother PC-FAX.v.2.1 and assigned it to IP the port I
just added.
I could not find a solution anywhere for this and the only suggestions made
were
re-install the OS. For a stable system other than this, I did not want to to do
that and then re-install several thousand programs.
During my research, I found MS making reference to a good print driver,
PRINTER.DLL. That caused me to search for a driver and when I didn't find it
anywhere on my system, I went and got one stumbling across one availablefrom
the Windows Update when I added my new printer.
I planned to place that PRINTER.DLL file into the folder recommended my MS, but
I found I didn't need to go that far. All I had to do was allow MS to offer up
the printer I needed (after allowing the full printer install package to
complete with the errors) and then assigning it to the TCPIP port found in my
printer.
If you have a similar 0x00000704 error, you may find this solution to apply to
you.
After months, my MFC-440CN works as advertized (as it had before I changed my
registry) to default my "Program Files x(86)" and "Program
Files" to default to drive "D".
I don't know that my change to the registry had anything to do with thiserror,
but I believe the key is finding a good driver from the Windows Update (by
adding a printer) and finding a good driver to download, followed by assigning
it the IP the printer has.
I REALLY hope this helps someone avoid re-installing their OS. This was one
hard
puppy for me to fix.
I would like to know if this helped you and if my post was worth while.
