However if you have any question around it, I would suggest to post in Windows Server forum: https://social.technet.microsoft.com/Forums/windowsserver/en-US/home?category=windowsserver

Hi,

How about the issue?

Please view the above article to know about the information about WMF version 4.

Are you installing exchange 2013?

If that is the case, you can refer to the below link to complete the installation:
