"Access is denied" is a pretty obvious error message is it not?

Member 9762654 20-Aug-13 7:18am

yes

You need to click on Improve question and add relevant code. If you want to get a file from IIS you just need the url.

You shouldn't do this. The server side automation of Office is not supported. http://support.microsoft.com/kb/257757/en-us

Right! That's the point. Please see my solution for the alternatives...

By the way, when you have IIS starting Word, where does it run? On which screen do you exoect it to be seen when you set wordApp.Visible = true;?
You ought to learn that IIS is not a Terminal Server - and understand the differences in the concepts.

You could run into different kinds of problem if you use Microsoft Office Interop for Word or other applications. This Microsoft article explains why using it in the server setting is discouraged:
http://support.microsoft.com/default.aspx?scid=kb;EN-US;q257757#kb2[^].

I suggest you use the alternative approach: Microsoft Open XML SDK:
http://www.microsoft.com/en-us/download/details.aspx?id=30425[^].

This way, you can support new XML-based Office formats (such as .DOCX, .XLSX), ECMA-376 standard:
http://en.wikipedia.org/wiki/Microsoft_Office_XML_formats[^],
http://en.wikipedia.org/wiki/Office_Open_XML[^].

This way, you can work without Office installed. Also, the documents are supported by 3rd-party software. Please see my past answers:
Convert Office-Documents to PDF without interop[^],
Need a rather unique WPF text editor control[^],
Hi how can i display word file in windows application using c#.net[^],
Read a word file without using Interop.word dll...Do not want to install word in IIS..[^].

This is another option: http://npoi.codeplex.com/[^].
