.NET Launching MS Word Programmatically while on Terminal Server Session

Greetings,

Our goal is to launch MS Word programmatically to a file we just created and saved to disk using a .docx template.

The catch is: we have to do this through a Terminal Server (virtual) session - logged into Windows 2008 R2 !

However, while we CAN successfully create directories, create MS Word files, and write these to disk through the TS session...we are NOT able to LAUNCH MS Word on the TS session programmatically. In other words, this "launch" portion is the only remaining part of the solution not yet working.

Furthermore, we ARE able to complete the launch using the following development environment / platform ...so we know the code "works"...:

- Windows 7 Workstation
- IE 9.0 Browser
- Microsoft Visual Studio 2010
- "Localhost" IIS App. Server
- Connecting to MS SQL Server

...and YES, we can launch MS Word 'manually' through the TS Session navigating to and then opening the file we JUST CREATED using .vb code...so we know that MS Word is working (appropriate CAL's, etc.) on the TS...

[ANY IDEAS WOULD BE GREATLY APPRECIATED ...THANKS MUCH!]

THIS CODE WORKS LOCALLY IN THE DEV ENVIRONMENT, BUT NOT THROUGH A TERMINAL SERVER SESSION:

=================================================================
Private Sub LaunchWord (_fileToLaunch As String)

Try
Dim WordApp As Word.Application = New Word.Application()
Dim WordDoc As Word.Document = WordApp.Documents.Open(_fileToLaunch)
WordDoc.Activate()
WordApp.Visible = True

Catch ex As Exception
'Response.Write("An Error Occurred: " & ex.ToString())

End Try

End Sub
=================================================================

Do you get any output? Errors, etc? Have you tried it in debug mode?

Good question, here is error page on server with error tracking turned on...

Again, manually launching the outputted MS Word file DOES work...

Note: "Line 389" is the end sub of the LaunchWord sub - referenced above - from my OutputWord class... ( and of course CreateDate is the next function)

Thanks!

Not only Terminal Services but using IIS! IIS runs in a sandbox and is designed specifically to disallow launching of executables outside of the sandbox. Which application pool is this using?

Can IIS be configured to allow specific exe's? Or, pass in some sort of pre-approved security token?
