I've created an Excel add-in using Visual Studio 2008. It has a ribbon, a bunch of panes and code that adds sheets and ranges and gets information scraped from a web page.

When I run it on my dev PC it works perfectly. I used the Publish command to publich it and installed on a Windows XP virtual PC. The installation seemed fine and when I open Excel I see my ribbon. If I click a button that shows a pane, up pops the pane. If I enter some details into the pane that should create a range and populate it with data from a web page, the range is created but the web page is not visited (I have tested that I have connectivity). One of my buttons adds a hidden worksheet and another displays or hides that sheet. One of these buttons is not working.

I've tried everything I can think of. I'm wondering if there are any permissions or trust issues I need to deal with?
