前几天我update了msn，变成了msn7.0.但今天提示我不能用了，要更新。我更新后才发现是msn6.2,说我已经装了更高级的版本，要删掉7。0。我删掉7。0再用6。2，6。2也不能用了，有谁知道是怎么回事吗？

请告诉我，谢谢！

but when i use the msn6.2, there is always a message shown"This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem."

but i have reinstalled the msn 6.2, it still has this message, whta should i do?

please help!

DO NOT install any beta version software, unless it has been officially claimed stable and reliable,expecially those don't-know-come-from-where version.

for you problem, suggest you reinstall windows or no longer use msn.

to all the people face the same problems as me, you use windows messager first, then if you want to send email to your friends through msn, the system will ask you "do you want to download msn messager?" you click "yes", then you can use.

otherwise if i download msn from website, there is always a error!

by the way, i do not dare to use any beta software la!
