My MP990 will scan using my Win 7 laptop but not with my XP desktop

[gooch]

I have been running my MP990 using a WiFi connection. I had to replace the printer with another MP990. I can still use the scanner function using the Win 7 laptop but not on the desktop XP. With XP, I get the following message:

Cannot comunicate with scanner for these reasons:

- Scanner is turned off

- Scanner is disconnected

(It is disconnected from LAN, if using on LAN)

Please check and try again

Scanner Driver will be closed

  Code:5,145,55

Since it will scan using the Win 7 "Windows Fax and Scan" but will not work on the desktop XP, I suspect I need to re-install the software. I don't have the orifinal disk but I did download  a couple of files: MP990soswin100us.exe or mpnx_3_0-win-3_05-ej-exe

Can I just run one of the above .exe files to take care of my problem?

Hi gooch,

I recommend installing both of the files you mentioned as one is the driver and the other is MP Navigator.  The driver will get the basic files installed, but the MP Navigator gives you an easy to use interface to power the scanner.

I installed the software but still having problems. I was able to scan bt saving to a flash drive. When I try to scan and save to my computer, I get an error saying something like "Cannoy to save to PC on LAN". So I figure I don't have my PC's with XP SP3 set up properly. My Windows laptop scans okay. I'll pursue the LAN issue some more.

I finally found the original CD that came with the MP990 and re-installed it after first removing all traces of the original program. That took care of the problem. It would have been helpful if I could downloaded the latest setup disk for the MP990 but I couldn't find any thing in the files section.
