Upgrade from Office 2007 to Office 2010 on a 64-bit OS Causes Visual Studio 2008 and Visual Web Developer 2008 Express Web Designer and Editor to Hang
This article has been archived. It is offered "as is" and will no longer be updated.
On a 64-bit machine with Office 2007 and either Visual Studio 2008 or Visual Web Developer 2008 Express, an upgrade to Office 2010 will cause Visual Studio 2008 or Visual Web Developer 2008 Express to hang when using the web editor or designer. The hang will reproduce by explicitly switching to design view on any web page (ASPX/ASCX/HTML/Master). It will also reproduce in a variety of actions inside the source editor of these pages, especially in cases where you have CSS in your page. Examples include pasting code, formatting, and using style-related functionality such as Apply Styles, Manage Styles, Build Style, or the CSS Properties. These symptoms will also occur after an explicit uninstall of Office 2007 on a 64-bit machine, which one would be required to do in order to upgrade to Office 2010 64-bit.
Note: This issue does not reproduce on a 32-bit OS.
The issue occurs due to incorrect removal of the 32-bit version of MSXML5 component by the 32-bit Office 2007 uninstall.
To resolve this issue, download the following update from Microsoft Download Center:
You can also work around this problem using these steps:
1. If an automatic upgrade was performed from Office 2007 (32-bit) to Office 2010 (32-bit) on a 64-bit OS:
In Add/Remove Programs, locate "Microsoft Visual Studio Web Authoring Component"
Right-click and select "Change"
When a dialog opens, choose "Repair" option
2. If you manually uninstalled Office 2007 on a 64-bit OS:
In Add/Remove Programs, uninstall "Microsoft Visual Studio Web Authoring Component"
If you are using Visual Studio 2008:
From the Visual Studio 2008 media, navigate into the WCU\WebDesignerCore folder and install WebDesignerCore.exe
If you were upgraded to Visual Studio 2008 SP1, you must reinstall Service Pack 1 for Visual Studio 2008.
If you are using Visual Web Developer Express: Uninstall and reinstall Visual Web Developer 2008 Express
