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!
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:
- Click Start, click Run, type %windir%\inf in the Open box, and then click OK.
- Find a set of eight files beginning with “BTH.INF”.
- Move following files to a temporary folder:
- bth.inf, bth.pnf
- bthpan.inf, bthpan.pnf
- bthprint.inf, bthprint.pnf
- bthspp.inf, bthspp.pnf
Follow these instructions at your own risk! Make sure you backup your computer before attempting this procedure. I can’t be held responsible if you screw up your computer.
