Have tried everything so far related to all of the most recent releases(Windows Live Messenger 8.1 and Windows Plus Live 4.81).
Uninstalled all MSN software, deleted all left behind folders, and used the ZapMessenger utility.
When I install "Plain Jane" Messenger, then WLM, and MsgPlus 3, I can get it to work without adding skins(Because they are all for Windows Live 2009 and 8.5/8.1. So when I try to install a skin, it says it is not compatible with my current WLM installation.
At this point, I get the Alert that there is a more recent version available, and I go ahead and download it. It turns out to be the Windows Live Essentials. I download it and run the exe. It starts installing after following the steps in the first few windows. I watch the progress bar climb all the way to 100%, then all of a sudden, it starts rolling back and uninstalling it. When it's finished, everything has failed to install and has a red X next to each item in the list. The message in the right window says that the installation was canceled with a cancelation # 0x80004004.
Now what really confuses me, is that a few days ago, I updated WLM to WPLM 4.81 and it worked. I imported Snow Leopard and was all happy until the next time I opened WPLM. It was back to just "Plain Jane" again, and that's when all this stuff began to happen.
Thank you in advance
