Live Messenger Error 2771 After Installing Windows XP Service Pack 3 (SP3)

Subsequent to successfully installing Windows XP Service Pack 3 (SP3), starting Windows Live Messenger (WLM) may pop up an install error. The error reads: “The installer has encountered an unexpected error installing this package. This may indicate a problem with this package. The error code is 2771.”

Error 2771 means there is a missing component. The simplest fix is to let WLM’s installer repair the issue automatically. If, however, the error dialog keeps popping up every time WLM is started then the suggested fix is to uninstall WLM from Add/Remove Programs in the Control Panel and reinstall the package from Microsoft’s website. This should correct the issue.

On a side note, some users out there don’t want Microsoft cluttering the Windows desktop with ads via WLM so they install A-Patch. The moral and ethical dilemma is up to the reader to sort out but Microsoft is providing instant messaging on an ad-supported model. If too many users do this then it could affect everyone’s free access. Choose wisely!

“Bluetooth Device Not Found” After Windows XP Service Pack 3 (SP3) Install

My Dell-branded Bluetooth module disappeared after installing Windows XP Service Pack 3 (SP3). The fix for this solution is pretty simple as long as your device was working prior to installing SP3. The steps are as follows:

  1. Click Start, click Run, type %windir%\inf in the Open box, and then click OK.
  2. Find a set of eight files beginning with “BTH.INF”.
  3. Move following files to a temporary folder:
    • bth.inf, bth.pnf
    • bthpan.inf, bthpan.pnf
    • bthprint.inf, bthprint.pnf
    • bthspp.inf, bthspp.pnf
  4. Click Start, click Run, type devmgmt.msc in the Open box, and then click OK.
  5. Expand the list under Bluetooth Radio by clicking the “plus” sign.
  6. Right-click “Microsoft Bluetooth Enumerator” and click uninstall. Click OK on the next dialog box.
  7. Right-click “Generic Bluetooth Radio” (it may read “Dell TrueMobile Bluetooth Module” or something similar) and click “Update Driver…”
  8. If a dialog box comes up asking “Can Windows connect to Windows Update to search for software?” click “No, not this time”, and then click NEXT.
  9. On the next screen pick “Install from a list or specific location (Advanced)” and click NEXT.
  10. Click “Search for the best driver in these locations.” and put a check-mark on “Include this location in the search:”. Then click BROWSE.
  11. Find the location where the Dell WIDCOMM drivers were installed. On my system this is “C:\Program Files\WIDCOMM\Bluetooth Software\bin”. Click NEXT.
  12. Windows will now install the drivers.
  13. Restart your system if necessary.
