Framework security should be set by the installer package or manually using
the Framework configuration utility. It's not set by installing or
reinstalling the Framework. For a VSTO addin you need to have full trust set
up for your addin assemblies. That's usually done with the SetSecurity
project as detailed at
http://msdn2.microsoft.com/en-us/library/bb332051.aspx. Those articles also
have information about deploying on Vista, and there's more information
about deployments at http://www.outlookcode.com/article.aspx?ID=42. I'd
suggest carefully studying all the information available at those locations.

If the addin sample from my Web site is working for you then it's a matter
of comparing your code and deployment with the sample and seeing what's
different. I can't do that for you.

If the property page is displaying on some systems and not on others then
you have to try and find out what's different. Again that's detective work
you'll have to do.

Hi Ken,
Further I need some clarifications from you.
1 Framework security setup : What is it? How can I check it? Can it
be fixed by installing .net framework again?
2 Dependencies in the project to make sure they exist or are
deployed : Actually I am confused with this part. I have checked my
addin on clean Vista machine without any development platform on it.
It worked for me. For that , I used totally formatted disk to install
Vista & office 2007. So my thinking is that I am deploying all the
necessary files to client machine.
3 Possibly adding lots of logging code : I have added trace after
each line. But as I said before, I can see the trace for
Applications_PagesAdd only & not a single line from Page_Load method.

Thanks again!
Dhananjay
