The following can be performed on the end-user workstation in order to resolve the problem:

1.  Open the System Properties

2.  Click on Environment variable

3.  Edit the System PATH environment variable, and add to the end of it the path to the Office 14 folder, as shown below:

The default entry to add will be either :-

4.  The system will need to be restarted following the change.
