Hi,

We have developed a VSTO 2005 Excel application and we would like to
leverage ClickOnce deployment mechanism for distribution of this
application.
How can we do that? I was digging in MSDN for VSTO & ClickOnce documentation
and did not find anything. I've noticed that there is an option to
publish the project, but when I do that and then run the application from
Web it throws us security errors like:

Is there another method we can use for automatic distribution of our
application if ClickOnes doesn't support VSTO?

Thank you very much for your help and support,

Best Regards,
