Desktop.Desktop_Update can't update Datastore settings

[Po-temkin]

Describe the bug

I tried to update Datastore setting using Desktop_Update.
What's wrong with my version?

Exception on call "Desktop_Update" with "2" arguments: "Failed to load type "VMware.Hv.String" from assembly "VMware.Hvi, Version=8.4.0.709, Culture=neutral, PublicKeyToken=null"."
string:1 symbol:2
+  $ViewAPI.Desktop.Desktop_Update($DesktopId,$MapEntryDesktopVirtualCenterStorageSettings)
    + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
    + FullyQualifiedErrorId : TypeLoadException
