Thanks again Bob, but putting the add-in file on a server won't work, as we
got lots of laptop users which must be able to work offline. Also I can not
tell each user to manually add the add-in using "Tools / AddIns" nor do it
personally (about 8000 machines worldwide...).
Right now our software deployment tool copies all project files onto users
harddisk and creates a link to the xla-file in the global excel startup
folder ({program files}/microsoft office/officeXX/xlstart. I just wasn't
sure if there are no side effects doing this or even a better solution.

Hi Luc,

When an addin is installed, it becomes part of the Excel client (or more
precisely, there is a link to the xla file within
Excel, which if the addin is checked in the addins list, it is loaded
each
time Excel starts, or when the item is checked).

Problem with the registry, apart from the health warnings which I am sure
that you are more than cognisant of, is that the registry entries are
re-built by Excel depending upon the addins list.

As I presume that you will load the physical xla file on the server, you
should have no problems wit the per machine basis.

Hi Bob, thanks for replying. Think I have the describe my problem a bit
more
precisely.

We install software using a deployment tool. Currently I should
distribute
an Excel add-in to all of our machines. To make sure the software is
installed independent from a user account, it should be installed on a
"per
machine" basis (and not per user).

If Excel does not allow this, how can a xla-addin be installed per user
but
without opening Excel? Are there any registry keys for doing this (like
for
PowerPoint add-ins)?

thanks, Luc

Hi Luc,

Put the xla on a server and then install from there.

Hi
I 'm trying to do a "per-machine" installation of an xla-Addin. How
can
this
be done?
Thanks for any hints!
