COM Add-in for Excel doesn't load when Excel is launched by opening file
- by Nick Hebb
Several users have reported that if they launch Excel by double-clicking an Excel file, the add-in will not load. But, if they open Excel via the Start menu (or Quick launch toolbar) the add-in loads fine.
Some details, in case they help:
It is a COM add-in, written in VB6.
The problem has been reported on Windows XP/Excel 2003 and Vista/Excel 2007 systems.
The add-in implements IDTExtensibility2.
The start mode is set to "Load on Startup".
Any thoughts on the cause or how to troubleshoot this would be greatly appreciated.
