Eliminating Prompts when opening PDFs from SharePoint using MacroView

Prompt 1: Some files can harm your computer.

If you receive the above message when opening a PDF file, the prompt can be suppressed by setting the setting below in the registry to 1

Computer\HKEY_CURRENT_USER\Software\MacroView\DMF\UserOptions\OpenFilesDirectFromUNCPath 

You may need to restart DMF for the change to apply.

Prompt 2: Check Out & Open, Open, Cancel

This is displayed by Adobe Reader as part of its improved awareness of SharePoint.  Various internet articles note that this prompt is displayed even if the user has read-only access…

To stop the above prompt following the steps below:

1. Open the registry.
2. Go to HKLM\SOFTWARE\Policies\Adobe\\\FeatureLockDown
3. Create a Key called cSharePoint
4. Create a DWORD value called bDisableSharePointFeatures
5. Set its value to 1
