I am trying to make a C# addin but having some trouble getting started. I can get the addin to show up in the list of available addins in Solidworks however when I hover over the Addin name it shows a popup with the Title and Description but the location of the dll is blank (all the other addins have the loaction of the dll listed). This makes me think that the registration process has failed somehow.... I have checked the "Make assembly Com Visable", "Register for COM" and target x64 platform options in Visual Studio.

I have tried to manually register the dll using the x64 version of regasm with the /codebase flag but still not working.

I am also getting a bunch of "Processing COM reference "SldWorks" from path ...." errors when I build the project.

I am using a win7 x64 machine with SW2013x64 (not SW2014x64 is also installed on this machine).

below is the declaration for the class:

    [Guid("91f0f2c3-c6a0-41a8-8a50-35188dd8a573"), ComVisible(true)]

    [SwAddin(Description = "New Description Here", Title = "Title", LoadAtStartup = true)]

    public class myAddinClass: SwAddin

    {

        public bool ConnectToSW(object ThisSW, int Cookie)

        {

            iSwApp = (ISldWorks) ThisSW;

            iSwApp.SendMsgToUser2("Addin Connected to SW",(int) swMessageBoxIcon_e.swMbInformation, (int) swMessageBoxBtn_e.swMbOk);

            return true;

        }

        public bool DisconnectFromSW()

        {

            iSwApp = null;

            GC.Collect();

            return true;

        }

        [ComRegisterFunctionAttribute]

        public static void RegisterFunction(Type t)

        {

            // Add the registry key that tell SW about the addin

            Microsoft.Win32.RegistryKey hklm = Microsoft.Win32.Registry.LocalMachine;

            Microsoft.Win32.RegistryKey hkcu = Microsoft.Win32.Registry.CurrentUser;

            string keyname = "SOFTWARE\\Solidworks\\Addins\\{ " + t.GUID.ToString() + "}";

            Microsoft.Win32.RegistryKey addinkey = hklm.CreateSubKey(keyname);

            addinkey.SetValue(null,0);

            addinkey.SetValue("Description", "Sample Addin");

            addinkey.SetValue("Title","Addin Title");

            keyname = "Software\\SolidWorks\\AddinsStartup\\{" + t.GUID.ToString() + "}";

            addinkey = hkcu.CreateSubKey(keyname);

            addinkey.SetValue(null,1);

        }

        [ComUnregisterFunctionAttribute]

        public static void UnregisterFunction(Type t)

        {

            // Remove the registry keys that tell SW about the Addin

            Microsoft.Win32.RegistryKey hklm = Microsoft.Win32.Registry.LocalMachine;

            Microsoft.Win32.RegistryKey hkcu = Microsoft.Win32.Registry.CurrentUser;

            string keyname = "SOFTWARE\\Solidworks\\Addins\\{" + t.GUID.ToString() + "}";

            hklm.DeleteSubKey(keyname);

            keyname = "Software\\Solidowrks\\AddinsStartup\\{" + t.GUID.ToString() + "}";

            hkcu.DeleteSubKey(keyname);

        }

    }

Any hints will be greatly appreciated.

Cheers
