title: VSTO 4.0 Runtime Download Missing from MS?
body: <p>We have code that checks for the presence of the VSTO 4.0 runtime and downloads it, if missing. This has worked fine until today. It seems the VSTO runtime file has gone missing from MS. Does anyone know anything about this? Can we tell our clients it's an MS problem and will be cleared up shortly? Google doesn't find any comments about the file being removed.</p>
  
  <p>Thanks.</p>
