After installing IE 8 on Vista, Visual C++ 2008's webbrowser-based wizard reports script errors and does not generate correct code. Looks like Visual Studio always inherit new IE features instead of opt-in. I have similar issues when upgrade from IE6 to IE7.

Adding devenv.exe to HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION with the value 7000 does not help.

Also reported in IE feedback

Same Issue here on XP - also resolved on WinXP by Uninstalling IE8!

Ran into the same issue running Visual Studio 8 on Vista SP1. Unistalling IE8 fixes the issue

i´ve exactly the same problem on win xp sp 3 using the visual studio 2005 and the new ie 8.0.

disable the warning of active-x controls in the security-settings of ie does not help.

actually i create new classes in my projects with vs6.0.

added, localhost, to compatibility view but nothing worked. Used IE8 and tried to surf to
C:\Program Files\Microsoft Visual Studio 8\VC\VCWizards\CodeWiz\MFC\Simple\HTML\1033\default.htm (the same place vis studio 2005 "Add Class" script tries to go to when the script error occurs) and I get a warning that "To protect your security, IE has restricted this webpage from running scripts or ActiveX controls that could access your computer. There's nothing I could do to stop IE from displaying this message. I tried to reduce the security setting to an uncomfortably low level but this didn't solve the problem.

I was unable to get the workaround to correct problem. Trying to paste the "URL" to the local file in my computer identified in the script error was unsuccessful.

problem also exists on win xp using vis studio 2005.
