The failure of unmanaged code(Delphi) consumes Com from .Net


we have  access  com dll developed c#,    when codebase register(regasm) local path, works fine. when codebase mapped driver, throws error "interface not supported" delphi7. fuslogvw.exe, find com dll has bound successfully.  tested use caspol.exe grant full trust mapped driver, like:

caspol.exe -m -ag 1.2 -url file://s:\comclass.dll fulltrust.

i'm wondering if managed com dll can not registered mapped driver????
