[Solved] SharePoint 2010: Obtaining STSUPLD.DLL without installing Microsoft Office

If you find that "Upload Multiple Files..." is greyed out or otherwise unavailable in SharePoint 2010 and you:

  1. Are running 32-bit version of Internet Explorer
  2. Don't have a copy of Microsoft Office 2007 or 2010 available
  3. Have added your SharePoint site to the Trusted or Intranet Security zone in IE

You can still enable this functionality by installing SharePoint Designer 2007. It's a whopping 200+MB file, but it's the only thing I've found that supplies and registers STSUPLD.DLL, the DLL required for ActiveX “STSupld.UploadCtl” generally provided by the pricey Office 2007+ Professional.

Thing's that didn't work? - Installing Access 2010 Runtime+SP1 - Installing SharePoint Designer 2010+SP1 - A reinstall of SharePoint Designer 2010 - Installing Visual Studio for SharePoint something Runtime - Installing Word Viewer

This file uploader is a nice clean interface primarily suitable for end-users. It has its limitations, however, such as only being able to upload 100 files at a time. If you need more flexibility, you can mount the SharePoint site using Windows Explorer. Check out this post for detailed instructions on how to mount an SSL encrypted site.
