I tried to install the solution on out pilot moss2007 server. At first, I inadvertently istalled it without any parameters. Then I installed it using the proper params (not sure if this has anything to do with it).

When I hit the site I get an access exception loading nalpp.dll. I installed it on another instance without any problems. I compared the web.config and the policy file on the two systems and they are identical. Any ideas of what to look at next, i'm at a loss short of changing the trust to Full.
