Troubleshoot Outlook Add-in Errors In Citrix

When using the EIOBoard Outlook Add-in within Citrix, you may encounter a popup box that contains the following error message:

Microsoft Outlook will not load the script language of for these forms. This option is not available. Reinstall Office 2000 and select (add components) then select <Execute from disk drive>.

Hitting OK may bring up the same error message again, and you may need to click through them up to a dozen times before it completely goes away.  The following method resolved this issue in a Windows Server 2008 R2 and Office 2010 environment.

  1. The outlvbs.dll file is the key module that executes the Visual Basic Scripting (VBScript) language on the application Microsoft Outlook.  Outlook uses VBScript to pull up the respective forms to show the data.
  2. Copy the outlvbs.dll from a physical machine (Example path: C:\Program Files\Microsoft Office\Office14) to the local machine.
  3. Export the registry which points Outlook to the path of outlvbs.dll.  The registry key path for Outlook 2010 is:


  1. Paste the outlvbs.dll file in the location C:\Program Files (x86)\Microsoft Office\Office14 on the Windows Server 2008 R2 Enterprise.
  2. If the exported registry key was from a 32-bit machine and copied to a 64-bit machine, the path in it needs to be modified.  Replace ‘Program Files’ with ‘Program Files (x86)’.
  3. Import the registry into the machine running the terminal server.
  4. Now the error message will no longer appear.
