Today I'm getting a FATAL ERROR - Acrobat Failed to Connect to a DDE Server on Windows Vista SP2. Just trying to view a downloaded PDF file. Searched the web, a lot of folks have the problem. No time right now. Just downloaded Foxit Viewer: http://www.foxitsoftware.com/pdf/reader/addons.php This worked! I'm now reading the PDF in FoxIt! Anyone has a better solution that could work with Adobe Reader? Comment, let me know! ---update--- I saw this:
Generally this error comes from an anti-virus program blocking the software from connecting. Check McAfee for any type of Software blocks or firewall issues. If that doesn't work then uninstall and reinstall the program and see if McAfee then pops up with a message asking you for permission to let it access the internet.at http://itknowledgeexchange.techtarget.com/itanswers/cant-open-pdf-files-in-windows-7/ so I stopped real time blocking with Avast. Result: Adobe Reader still not working with this file...
