I’m running windows Vista x64.
Yesterday I downloaded Windows Live Messenger.
When clicked windows live Messenger appeared an error : sidebyside error
I followed the information given by the Event Log, and I found both Manifest, but really I don’t what to do with them. I'm not sure how to solve this problem.
Also I found that I have two Messenger installed.
I hope you can open the link and see all the information that I got.
