    Joe,

    >From the exception description, it looks like MagicLibrary probably has some
    assembly-level minimum permission requests. To discover which permissions
    are being requested, you could use either permview.exe
    (http://msdn.microsoft.com/library/en-us/cptools/html/cpgrfPermissionsViewToolPermviewexe.asp)
    or a disassembler like Reflector (http://www.aisto.com/roeder/dotnet/).

    HTH,
    Nicole
