SharePoint 2007: Multiple Upload Not working (or not available)

Sometimes SharePoint users notice that Multiple Upload is not available when trying to upload documents. This usually has to do with their company security settings.

The following conditions are needed to have Multiple Upload working:

1. At least Office 2003 must be installed.
2. Enable the ActiveX controls:
   2.1 Go to Internet Explorer > Tools > Internet Options > Security Tab
   2.2 Here in the "custom level' button activate/enable the Active X controls that say "Script ActiveX controls maked safefor scripting*", like in the image below:

You can also check the following:

1. Check that the Windows SharePoint Services Support component (under 'Office Tools') has been installed by the Office setup program. This installs an ActiveX control that provides functionality such as support for uploading multiple documents within IE. If it does show as installed use the Repair option so that Office setup can ensure it is installed correctly.

2. You can check if the upload ActiveX control is installed correctly by going to Manage Add-Ons in IE8 (or 7). Set the filter to show 'All Add-Ons'. Under Toolbars and Extensions look for the STSUpld UploadCtl Class and ensure it is enabled. It should have a major version of 12, for example 12.0.4518.1014 > not sure if it is this version without Office 12.

Good Luck!
