Hi Alan,

Installing a VSTO solution to HKLM will "work" in Outlook 2003 but is not
supported. As Ken already noted in Outlook 2007, VSTO solutions will _NOT_
work if they are registered in the HKLM hive (i.e.
HKLM\SW\Microsoft\Office\Outlook\Addins\).

Here is more information that may be helpful (at least for Outlook 2007)

I want to install my addin to HKLM rather than HKCU so that all users can use
it. I can make the necessary registry changes to the setup project and
install it as administrator and it works OK for all users - but only if they
are administrators.

There is conflicting evidence on the web: this MS article tells you how to
do it - so you would figure it was supported:

but I have seen Ken Slovak responses suggesting this is not supported...eg:

Can anyone give me a definitive answer on this? Is there any way out?

I hope so because it will cost me a 6 figure sale - not to mention the six
months of work thats gone into it. Help!
