Error: new failed TrioDM : APIS_91_WSDL::InitAPIS : APIS_91_UNIT : FosMobile.dll System Message: Microsoft MSXML is not installed

The following error may be seen on a user-by-user basis when attempting to file 91 APIS from FOS.

Error: new failed TrioDM ; APIS_91_WSDL::InitAPIS : APIS_91_UNIT : FosMobile.dll
System Message: Microsoft MSXML is not installed


Solution:

This is a workstation fix, not a data/config issue:

  1. Have IT open an elevated command prompt and run:

    regsvr32 msxml6.dll

    If that returns an error, they may need to repair the file first from Windows installation media or SFC:

    sfc /scannow
  2. Alternatively, downloading and re-running the Microsoft XML Core Services 6.0 installer (available from Microsoft's download center) will re-register the COM objects.

  3. Once MSXML is re-registered, Lucas should be able to submit APIS 91 without error. No FOS data changes are needed.
