Deploying VSTO Word Project: could not find or load customization assembly

Deploying VSTO Word Project: could not find or load customization assembly

• Annddrew

  Hi.

  I'm too am experiencing a few problems getting my VSTO Word customisation to run.

  I'm running Visual Studio 2005 Professional.

  I created a local web site http://localhost/AnotherTest

  The web app consists of Default.aspx with a single button.

  The code-behind the button is as follows:

  
  Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click

  Dim file As FileStream = New FileStream( _
  "C:\Inetpub\wwwroot\AnotherTest\MyDoc.doc", _
  FileMode.Open, FileAccess.Read)
  Dim template As Byte()

  Try
  template = New Byte(file.Length) {}
  file.Read(template, 0, CType(file.Length, Integer))
  Finally
  file.Close()
  End Try

  Dim sd As ServerDocument = New ServerDocument( _
  template, ".DOC")

  Try
  sd.CachedData.HostItems("MyDoc.ThisDocument"). _
  CachedData("TestData").SerializeDataInstance( _
  "Hello")
  sd.Save()
  Finally
  sd.Close()
  End Try

  Response.ClearContent()
  Response.ClearHeaders()
  Response.ContentType = "application/vnd.ms-word"
  Response.OutputStream.Write(template, 0, template.Length)
  Response.Flush()
  Response.Close()

  
  End Sub

  I created a VSTO Word document project called MyDoc containing a line of text and a single bookmark.

  The code-behind is as follows:

  
  Public Class ThisDocument

  <Cached()> Public TestData As String

  Private Sub ThisDocument_Startup(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Startup

  Me.Bookmark1.Text = Me.TestData

  End Sub

  Private Sub ThisDocument_Shutdown(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Shutdown

  End Sub

  End Class

  I published the document to http://localhost/AnotherTest

  I ran caspol -ag 1.2 -url http://localhost/AnotherTest/* FullTrust

  When running http://localhost/AnotherTest/MyDoc.doc from Start/Run
  or
  Clicking on the button in the web site and clicking Open I get the following message:

  The customization does not have the required permissions to execute.

  Can anyone help me

  Even I have tried multiple ways to get the customization trusted and working but it did not work.
  
  Only method it worked with the following steps :
  
  1. Add the msosec.dll in Assembly cache
  2. Add a new code group with full trust to MSOSEC.xml
  
  Now Word should ready be for taking customization.
  Assuming PIA are also installed in this Office installed (.net programability support)
  
  3. This is part where alternative did not work till now.
  Place the .dll of the Word project into GAC after signing it with strong name.
  
  This solution worked for deployment to the web server with a URL similar to this.
  http://son10325/WordDocument4/WordDocument4.doc (for local & intranet machine access)
  and
  http://localhost/WordDocument4/WordDocument4.doc (for local machine access)
  
  This was accessible from the local machine as well as another machine in the intranet through the same URL.
  
  Please tell if anybody has an alternative to avoid placing in GAC but with rest of the scenario remaining same.

  hi akois,

  I'm sorry, but I never did get this stuff to work correctly. For the moment I can manage without it, so I stopped trying to figure it out - but I will have to get back to it.

  hi guys,

  i got the solution

  Please check the following points:

  1. Install the .Net FrameWork 2.0 and Visual Studio Tools for Office runtime on the client computer.

  2. Edit the security policy of .Net FrameWork 2.0 configuration with the following steps at client computer:

  1) Go to Control Panel > Administrative Tools > .Net Framework 2.0 Configuration

  2) Go to My Computer > Runtime Security Policy > Machine > Code Groups > All_Code and add a new code group

  3) Give a Code group name, say next and select the condition type as URL and give the URL where you put ExcelWork1.dll

  For example, if you put the dll in \\server\ExcelWorkbook1\bin\Debug\ExcelWork1.dll

  Please type \\server\ExcelWorkbook1\bin\Debug\* (access directly to server) . or Http://ExcelWorkbook1/bin/Debug/* (access from web)

  4) Do next and assign Full Trust and say finish.

  thats all..i hope its help..

  That step is no longer needed, and it has been removed from the documentation going forward. You can follow the procedure and just skip over the part about adding msosec.dll to the fully trusted list.

  Has anyone gotten this to work
  

• radioman

  Thank you very much -- When I get back to it, I will try skipping that step. Can't wait to get caught on a future step!

  I saw this old post and I am getting the same error. I'm new to VSTO and am trying to get this to work. Using VS2005/VSTO, I created a Word doc that reads and displays data from an XML file. I want this to work on the client's web server so they can get a Word report based on data generated in the XML file.

  I'm using VS2005 and when I run/debug the solution on my PC it works fine. I published the solution to the web server. When I try to browse the .doc in IE from the web server I get the error:

  -------------------------------------------------------

  The customization does not have the required permissions to execute.

  The Zone of the assembly that failed was:
  MyComputer

  ...............

  ----------------------------------------------------------------------------------

  I followed the instructions on the following pages to give the assembly and document full trust (I used the .NET 2.0 Configuration tool):

  http://msdn2.microsoft.com/en-us/library/zdc263t0.aspx

  http://msdn2.microsoft.com/en-us/library/9w6bd8f1.aspx

  I'm very unsure about how the server and client need to be configured. One obvious question, does Office need to be installed on the server Also, should I need to do any additional configuration on the settings on my computer (the client for this test). I already have the 2.0 framework and VS2005 (obviously), so I'm assuming that should be all I need. I'm not sure where to go from here.

  Thanks for any help or insight.

  Hi Ken,

  I am having the same problem as Ricardo, except in Excel. I tried to follow the steps in the link 9w6bd8f1. When I got to step 2, to add msosec.dll to the fully trusted assembly list, I got an error about a key and a secure name -- sorry it was at work, I'm home now and don't remember the exact error. Should I have expected that

  Thanks for any help you can provide.

  No, you can ignore that message and just keep going. Msosec.dll does not need a strong name, and your solution should work fine. You do not need to add msosec.dll to the trusted assemblies list.

  Hi Ricardo,

  If the users are going to be opening the Word document from the shared folder on the server then you also need to setup a .NET security policy to trust the location where the document resides.

  I've included a link below to the help topic "How to: Grant Permissions to Documents and Workbooks in Shared Locations" which I think should resolve the security issue.

  Hi Harry:

  I have the same errors and I tried to follow the steps, but I got the message said Msosec should have a strong name. Checked with Policy Assemblies and could not see Msosec already there. Should I use tool to make Msosec a strong name

  Thanks!
