For doing this, you would need to either preview the dashboard in Dashboard designer or do an "Export preview" (File >> Export preview).
When the dashboard SWF loads, follow the below steps:
- Right-click inside the SWF file and choose 'settings'
- Adobe Flash Player Settings dialog will appear.
- Click on 'Advanced' within the Privacy tab
- Your default web browser will launch and take you to Macromedia's Settings Manager
- In the Settings Manager, click on'Global Security Settings Panel'
- Make sure that 'always Allow' is selected
- Click on the dropdown box and choose 'Add Location'
- add: 'C:\' (without the apostrophes)
Along with C:\ also add the server host name that you have defined in the Live Office connection URL.
The detailed steps for this are mentioned in the following kba:
