I developed an Excel Add-In for Excel 2003. I was using registry entry to
include the folder where the xla is kept. Due to this registry entry I was
getting the name of the xla in the list of Add-In manager.

Now I am testing the same Add-in in Excel 2007, and doing the same registry
entry to include the xla name in the Add-In Manager List, but some how it is
not working. Even if I include the xla manually by browsing it in Add-In
Manager, as soon as I close the excel and open again, the name of the xla
added last time goes away and again I have to include it manually. I dont
want user to include the xla every time manually.

I dont know what settings I need to change in Excel 2007 (or registry
entry). Please help.
