Versions:
vCenter 5.5
Update Manager 5.5
Esxi 5.5
We have a client that has vCenter 5.5 installed using VUM (Yes I understand unsupported). I have seen in another question but no definitive answer hence my question as to the issue relating to the fact that version 4 of Microsoft's XML Parser engine (DLL) is no longer supported and needs to be removed / unregistered.
The vCenter server has both msxml3.dll and msxml6.dll installed with the CLSID pointing to msxml3.dll. On the post which I found referenced here: https://kb.vmware.com/s/article/2113837 it states that there were issues with upgrading to version 6 which and the download process for VUM.
My question is this: Is the vSphere vCenter client and COM written application (C++) or is it .NET written in C# and therefore uses different .NET assemblies and not COM?
I want to disable the version 4 by doing an unregister of the DLL via: regsvr32 /u msxml4.dll and also rename the file but I do not want to break the functionality of VUM. If version 6 msxml6.dll is already installed on the server will version 5.5 VUM work with this or does it require msxml4.dll specifically?
Thanks
