Load an Addin into DraftSight

These days i am developing two plugins for Autocad 2012 & DraftSight 2013.so when i was developing the plugin i got in to big trouble.Normally in the Autocad , we can load the .dll file simply typing the command "NETLOAD" but in the Draftsight i could not able to do that. It said 
" D:\c \projects\c projects\DSAddinCSharp1\DSAddinCSharp1\bin\Debug\DSAddinCSharp1.dll is not a valid add-in"



Finally i got the solution ... :)
You need to register the addin to your Windows system. For example, if the system is .NET 4 framework of 64 bit.
Please refer below for the steps to register the add-in:
1)      Open a Windows Command Prompt.(Run as an Administrator)
2)      Change directory to folder C:\Windows\Microsoft.NET\Framework64\v4.0.30319 (or the .NET current version)
3)      Type this command with those options:
               regasm /codebase /tlb "<Windows path\adding name>.DLL" 
4)      If the addin DLL was registered successfully, the Windows Command will return this message:
 "Types registered successfully. Assembly exported to 'C:\<addin name>\.tlb', and the type library was registered successfully"
5)      Load the addin in DraftSight.

Note: If you are trying to register Release version.dll please run Windows command prompt as an Administrator. For this select select 'Run as an Administrator' from right click menu.


Hope this helps!
