IIS8 The Just-In-Time debugger was launched without necessary security permissions - asp.net

Question

Windows Server 2012 64 bit
IIS8
ASP.NET Framework 4
Trying to run an unmanaged DLL from my aspx page
Executing the DLL Function call gives:
The Just-In-Time debugger was launched without necessary security permissions. To debug this process, the Just-In-Time debugger must be run as an Administrator. Would you like to debug this process?
There is no debugger that I know of on the web server, trying to launch it gives errors.
Why is my call to my DLL crashing my aspnet worker process?
How can I tell IIS8 there is no debugger?
I have googled this extensively, and all the help seems to be about Visual Studio, not IIS. There is no Visual Studio on the web sever.
Here is the offending code.
private string regname = "";
private string fingerprint = "";
private string unlockingcode = "";
/// <summary>
/// called from page_load
/// </summary>
private void CreateUnlockingCode()
{
UInt32 lfp;
string sfp = fingerprint.Remove(4, 1);
lfp = Convert.ToUInt32(sfp, 16);
string bindir = Server.MapPath(#"~/bin/CodeGen64.dll"); //full path to the DLL "P:\\AFI2013\\bin\\CodeGen64.dll"
IntPtr pDll = NativeMethods.LoadLibrary(bindir); //attempt to load the library
try
{
IntPtr pAddressOfFunctionToCall = NativeMethods.GetProcAddress(pDll, "CreateCode2A");
CreateCode2 createCode2 = (CreateCode2)Marshal.GetDelegateForFunctionPointer(
pAddressOfFunctionToCall,
typeof(CreateCode2));
//THIS LINE CRASHES THE ASPNET WORKER PROCESS
unlockingcode = createCode2(1, regname, encrypt_template, lfp, (UInt16)0, (UInt16)0, (UInt16)0, (UInt16)0, (UInt16)0);
}
finally
{
bool result = NativeMethods.FreeLibrary(pDll);
}
}
And here is the Error from the Event Viewer.
