deploy security policy through a MSI

[beral]

Hello,

I have created an VSTO application related to Excel.

I have created all the security policy so that the Excel file have the autorization to load the dll created by my application. My problem is that I want to deploy my application by allowing the users to download the Excel file and the associated dll with all the adequate security.

I know that I have to create a .msi file.

But the Excel file is on a server and I would allow the user to download it and by that to launch the msi so that all security will be installed automatically.

Is that possible or am I just dreaming?
