When you open a Microsoft Excel workbook (.xls) or add-in (.xla) that uses the RefEdit control, you may receive one of the following unhandled exception error messages in Microsoft Visual Basic for Applications (VBA) on the first line of code in the project:
Error -2147467259 (&H80004005) : "Unspecified error"
The problem occurs if multiple instances (for example, four or five) of Excel are running. Each instance of Excel contains workbooks or add-ins that also use the RefEdit control, and all of the temporary locations that hold extenders already have open libraries by the same name (one for each instance of Excel that is using the RefEdit control).
Automation Error: The process cannot access the file because it is being used by another process
When a Microsoft Visual Basic for Applications (VBA) project that contains the RefEdit control is loaded, VBA creates a control extender for the RefEdit type library. The formation of the control extender is similar to any control that you add to a UserForm. If multiple instances of Excel are running, Fm20.dll may fail while it attempts to create this extender. This failure can result in a VBA runtime error when your code is called.

Service Pack InformationThis problem was first corrected in Office XP Service Pack 3.To resolve this problem, obtain the latest service pack for Microsoft Office XP. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:
307841Because the error occurs before the macro code is run, Excel starts the Visual Basic for Applications (VBA) Integrated Development Environment (IDE) and stops at the function entry point. This is similar to the behavior that occurs if VBA detects a compile error.
