reference to mshtml.dll working on integrated vs2005 server but not when deployed to IIS 2003 server

You need to ensure the HTML Help redistributable package is installed.

I get the following error : html help 1.3 cannot be installed on windows 2000 - I am running windows server 2003.

CAUSE
The HTML Help 1.3 viewer components are already installed on Windows 2000 as system components and cannot be updated using Hhupd.exe.

I found two other possible ways to fix the problem. First, you can copy Microsoft.mshtml.dll into the application directory. Alternatively, you can run vs_piaredist.exe, which is in \program files\common files\merge modules on machines with vs 2005 installed.

I'm not sure if this is the same problem but, ostensibly, it seems to be...

... it describes a solution.

I also found this solution - and I have tried copying the mshtml.dll file into the bin directory of the website and referencing it from within web.config. That did not help - still same error. As for the vs_piaredist.exe - I am not able to install vs2005 onto the IIS windows 2003 server. Can vs_piaredist run without vs2005?

As far as I can tell looking at other forums you'll need to redistribute it with you application and run it. This, apparently, will install the interop assemble into the GAC. I don't have a machine without VS on it so I can't try it for you I'm afraid. Sorry.

I don't think I can really tell you much more as at this point I am just Googling -- something I'm sure you can do just as well as me :)

"...The HtmlEditor has a dependency on Microsoft's MSHTML primary interop assembly, Microsoft.mshtml. This PIA will be installed on all systems that have Visual Studio Standard edition or higher. Systems with only express editions of Visual Studio will have to install Microsoft's vs_piaredist.exe redistributable or the .NET Framework SDK in order to acquire this prerequisite..."

thanks - I got it working by installing the vs_piaredist.exe on the server but it is painlessly slow.

Glad I could help :)
