Compilation of office COM Add-in solution

[alex30]

I have 2 computers:

1. Win7, Office2007, VS 2010
2. Win XP, Office2007, VS 2010

I've created COM Add-in for office applications.
If I build it on the second computer, Office applications successfully load it on both computers.
But, if I build it on the first computer, Office applications don't load it on any computer.

Do you have any ideas for troubleshooting?

Thank you.

As long as the 32/64 bit versions of the COM addin and office are the same, they should work together. Also ensure the COM addin is registered on the system through either self-registration or regsvr. Also check the registry under hkey classes root to make sure the component is listed there and follow the CLSID and make sure it is pointing at the right dll or ocx.

Those are my first thoughts.

you clearly have a setting on the win7 machine that does not generate the downwardly compatable code

or the code is fine for xp and the win7 machine accepts the older code.

like many upgraded systems the new ones understand the old bits but the old bits havent got a clue about the new stuff!

compile everything on the xp machine, job done, compatability maintained!

you'll be a super star
