When I double-click a linked or embedded object, I get a message saying the file can't be opened.

Microsoft Access displays this message when it can't open the source file for an OLE object. Check to make sure that:

• The application needed to edit the file is installed on your computer.
  
  
• You have enough memory to run the source application. Close other applications to free up memory.
  
  
• If the application that you're trying to open is already running, make sure that it doesn't have any open dialog boxes.
  
  
• If it's a linked object, make sure that someone else doesn't already have it open.
  
  
• If it's a linked object on a form, make sure that the name of the source file hasn't changed or that the source file hasn't been moved. To see the name of the original file, click the object, and then click OLE/DDE Links on the Edit menu. The original file name appears in the Links box. If the file has been renamed or moved, click the link in the Links box, and then click Change Source to reconnect the link.
