Configure update manager 5.5 to use a different version of MSXML for security reasons

Versions:

vCenter 5.5

Update Manager 5.5

Esxi 5.5

Hello.  It looks like update manager 5.5 uses C:\Windows\SysWOW64\msxml4.dll which is flagged as a critical vulnerability.  We need to remediate to the most recent version.  Updating the dll is no problem but what do I need to do to get Update Manager to look at the newly deployed MSXML dll?

Thanks in advance for any info you can provide,
