Microsoft Visual Studio Web Authoring Component fails to install.

1. Pre-release Office 2007 components are installed. Most often it was XPS Add-in for Office 2007.

2. Expired trial version of Office 2007 is installed.

3. Some Office components are installed, but are not visible in Control Panel.

Solution: uninstall offending component. You can verify if Office is RTM by checking version of MSO.DLL in C:\Program Files (x86)\Common Files\microsoft shared\OFFICE12. Right click on MSO.DLL and choose Properties -> Details version number should be 12.0.4518.1014 or higher. Typically it looks like 12.0.6xxx.yyy if

2. Make sure you have SP1 installed since . Go to Control Panel, click 'View installed updates', look for Visual Studio 2008 or Visual Web Developer Express 2008 and check that KB 945140 update is installed.

3. If everything is installed correctly, but switch to design view still does not work, look at this blog post:

4. Run regedit.exe and look for HKEY_LOCAL_MACHINE\Software\Microsoft\Office\12.0\Common\ProductVersion key. If key is missing, add it and set LastProduct value to 12.0.4518.1066. Simplest way is to create a new .reg file in Notepad, paste the following content into it

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\12.0\Common\ProductVersion]

"LastProduct"="12.0.4518.1066"

Save the file and double-click on it.
