Still cannot resolve this error and now msn's site is not working. I'm going to have to give up trying msn messenger.

Error:

 Activation context generation failed for "C:\Program Files\Windows Live\Messenger\msnmsgr.exe".
Error in manifest or policy file "" on line . A component version required by the application conflicts with another component version already active.


Conflicting components are:

Component 1: C:\Windows\WinSxS\manifests\x86_microsoft.vc90.crt_1fc8b3b9a1e18e3b_9.0.30729.4148_none_5090ab56bcba71c2.manifest.
Component 2: C:\Windows\WinSxS\manifests\x86_microsoft.vc90.crt_1fc8b3b9a1e18e3b_9.0.30729.1_none_e163563597edeada.manifest


I navigated to these components and the system won't allow me to delete either of them.
