SecurityException thrown for each build

Question

I have an application that I have placed on our LAN. I have each user "Trust" the assembly. The assembly runs fine for each user. My problem is when I perform any program updates and then copy the new build over my existing myApp.exe file on the LAN. Any time I update the application like that, all the users have to reset the trust to "full". Is there any way to set the permissions on the user's machine or configure my assembly so that new builds do not have to be re-trusted? My "AssemblyInfo" file does have the entry "[assembly: AssemblyVersion("2.0.*")]" which designates all builds and revisions, but this does not appear to effect the trust.
