This is a workstation fix, not a data/config issue:
Have IT open an elevated command prompt and run:
regsvr32 msxml6.dllIf that returns an error, they may need to repair the file first from Windows installation media or SFC:
sfc /scannowAlternatively, downloading and re-running the Microsoft XML Core Services 6.0 installer (available from Microsoft's download center) will re-register the COM objects.
Once MSXML is re-registered, Lucas should be able to submit APIS 91 without error. No FOS data changes are needed.
