Recently some of our user’s laptops were replaced with new laptops running Windows 7 64-bit. Right after this upgrade, some users noticed they could no longer open SharePoint 2007 libraries in explorer view and they no longer had the option to “upload multiple documents” from within the SharePoint libraries. Users with older 32-bit laptops running XP or Vista didn’t have this problem, so we knew it must be something with either Windows 7 or the 64-bit machine.
Numerous blogs recommended running a repair through Office diagnostics (Start > All Programs > Microsoft Office > Microsoft Office Tools > Microsoft Office Diagnostics ). We did this on one of the user’s new Windows 7 laptops and they still could not open SharePoint libraries in explorer view or upload multiple documents.
The problem ended up being the version of Internet Explorer. The new 64-bit Windows 7 laptop had both a 32-bit version and a 64-bit version of Internet Explorer as seen in the screen shot of the Start menu below. The default had been set as the 64-bit version. When the 32-bit version of Internet Explorer was selected, SharePoint performed as expected. The libraries could be opened in explorer view without error and the option to upload multiple documents was available.
I found lots of blog entries about different things that could cause this issue, but none that stated it might be the 64-bit version of IE.
