Calling Excel from a web browser via activex

I have some code that calls excel via Internet Explorer to plot some captured  by another executable.  When this occurs, I get the prompts from IE telling me that I have to authorize this access.  I understand that in order to make this prompting go away, I need to do the following?
Add the site to my trusted sites

Change the following IE settings:

Run ActiveX control = enable
Automatic prompting for ActiveX control = disable
Intialize ActiveX control not marked as safe = enable

Trouble is,  this is not a site I am adding, it is a file:

C:\Users\me\Appdata\temp\something.  When I try to add it to the trusted sites, IE gives me an error saying it is not in http:// format.

What is the best (simplest, least aditional overhead) method for getting my file to work?  I need it to work through IE so the rest of the system operates.   I also don't have any security concerns - this computer will run inside a closed network with no internet access.

Thank you for your assistance.
