What are the client side requirements to enable the "upload multiple files" link? I'm using WSS 3.0. Also using FBA, not sure if that matters. It "works on my machine", but not for some other users.
Here are the requirements for 'upload multiple files'
- The 32 bit version of Internet Explorer. The 64 bit version does not support it and neither do other, non IE, browsers.
- The STSUpld.UploadCtl IE add-in must be enabled.
- Office 2003 or newer on the client
- Client integration will need to be enabled for the web app.
For details see this post.
If a 64Bit edition of office is installed, it also won't work. You need an installed 32bit component of office. This deploys the required STSUPLD.DLL to
C:\Program Files (x86)\Microsoft Office\Office14.
Today we solved the issue by installing the 32bit version of SharePoint Designer 2010 side-by-side with a 64bit Office 2016.
