How to fix “Incorrect MFC Dll version installed on the system”

This post will cover the annoying error message that you might be getting on your machine. The whole error message is: “Incorrect MFC Dll version installed on the system,minimum requirement is MFC SP4 Dlls”. What this error message is refering to is Dell’s Wireless Network manager that ships on machines like Inspiron 9400s.

The reason why you get the “Incorrect MFC Dll version installed on the system,minimum requirement is MFC SP4 Dlls” message is there is some corrupt files that are part of Dell’s wireless system tray. It’s a pig on memory and you don’t really need it. I recommend that you just make sure that you use the built in Windows Wireless manager.

To get rid of the error you have to go into:

  1. START – Control Panel – Administrative Tools – Services
  2. Find “Dell Wireless WLAN tray Service”
  3. Right click the service and select “STOP”.
  4. Wait for the service to stop
  5. Double click the service.
  6. Make sure “STARTUP TYPE” is set to “Disabled”.
  7. If there are any “Incorrect MFC Dll version installed on the system,minimum requirement is MFC SP4 Dlls” on the screen close them. It should not re-apear again if you followed the steps correctly.

To switch the machine over to the built in Windows Wireless Manager follow these few steps:

  1. Click  “My Computer”
  2. In the address  bar type “Desktop” and hit Enter
  3. Find “My Network Places” right click it and select “Properties”
  4. Fine the Wireless Network Connection icon. Right click it and select “Properties”.
  5. Click on the second tab labled “Wireless Networks”.
  6. Make sure that “Use Windows to configure my network settings” is checked off.
  7. Noww you must click “Add” button to add your wireless network info. You will select the SSID network name and then you must enter your router’s wireless password.

I hate it when Manufacturer’s add their crappy bloatware to their machines!

I hope this helped you get rid of the  “Incorrect MFC Dll version installed on the system,minimum requirement is MFC SP4 Dlls” message!

  3. I’ve only ever seen this message on Dell machines. Is you’re a dell?

  5. It worked but I still can’t connect to my wireless network. I’ve gone all the way to step 7 of the second section above.
    When I uncheck it, the “ADD” option becomes un-clickable.
    everything was working fine two days ago. I’ve tried everything. System Retore refuses to even retore to past dates. :(

    Also using a Dell

  7. This particular error is preventing me from logging in on a virtual PC. I do have a snapshot I can roll back to. Thanks for posting this though.

  9. Yahoo! Your instructions for disabling Dell’s wireless program totally worked! I attempted to fix this issue for 3 years with 2 IT friends and could never find workable instructions online. Thanks SO much, Jared. Your instructions were clear, easy to follow, and empowered me to understand more about how my computer can be managed. I now also have a better sense of what bloaware is. The instructions for switching to Windows wireless manager didn’t quite work, but when I got into my wireless network connection properties, it appeared that Windows was already set for my wireless network settings. So, I think my machine is ok. Bless you!

  17. If you like I provide remote help services if you need more help than what I wrote out. If you decide to go that route use the contact form to PM me and we can work through it.
