As you may or may not know, Microsoft is discontinuing support for their MSN Messenger/Live Messenger service in favor of Skype soon.
Since Live Messenger is no longer needed on my system and this is part of Live Essentials, I tried to uninstall Live Essentials using the uninstall option of Programs and Features.
This repeatedly failed with error code 0x8007064c.
I did some searching and found this page which supplied the following solution:
Below are the steps on how to uninstall Windows Live Essentials via CMD line parameter.
a. Go to Start->All Programs->Accessories
b. Right click on Command Prompt and select Run as Administrator
c. Run the following commands to uninstall Windows Live Essentials:
· (64 bit) "c:\program files (x86)\windows live\installer\wlarp.exe" /cleanup:all /q
· (32 bit) "c:\program files\windows live\installer\wlarp.exe" /cleanup:all /q
d. A dialog box shows status until uninstallation has completed
Note: The uninstaller for Windows Live Essentials 2011 can also be downloaded fromhttps://g.live.com/1rewlive4arp/wlarp.exe if the local copy is corrupted.
The command worked successfully.
