I have an existing version of an Excel 2003 add-in, built using VSTOSE, that's working fine.

I would like install a new UAT version of this add-in, alongside the current add-in. I've tried to to do this, but each time I build one version of my add-in it just overwrites/overdeploys the other version.

The steps that I've taken are:

1)Copy my existing project;

2)Rename everying to a new name, including dlls, assembly name etc.

But unfortunately this still doesn't work. Can anyone help

Many thanks

I've managed to resolve this now....

It seems that copying the existing project wasn't a good idea. By creating a new project and copying all the individual files into the new project, everything seemed to work
