Connect to dotnet datatype in Dynamics NAV 2016 (64 bit) client side

in NAV Three Tier
I upgraded a customer database from NAV 2015 to NAV 2016.
In NAV 2015, Chilkat dll (32 bit) client side was used, and this works fine.
After upgrading to NAV in 2016, I removed old Chilkat 32 bit dll from folder "Microsoft Dynamics NAV / 90 / Add-ins" and new 64 bit dll awas copied to the folder (.NET 4.5), since it is not possible to load a 32-bit dll from a 64-bit NAV 2016 client.
Now I have two problems:
1) When I have to choose my 64 bit Chilkat dll, the old 32 bit dll is still displayed in Assembly List (although it was removed). I choose my 64 bit dll, but it is the 32-bit DLL there will be chosen. The code will compile, but when I execute the code, I get the error: "Can not load an instance of following .NET Framework object: assembly ChilkatDotNet45 ..."
2) I copy Chilkat 64 bit dll to Add-ins on a machine that have not used these dll. From the development environment, when I choose this Chilkat 64 bit dll, I get the error: "Could not load type 'ChilkatDotNet45 ..."
I get the same error when load of Chilkat dll type .NET 4.6
Any suggestions ?

    You already properly did this but:
    1.) Delete the dll (both x86 & x64) from Server and Clients Add-In Folders to make sure everythings clean.
    2.) Copy the dll only to the Server Add-In Folder
    3.) Restart Service
    4.) Try creating your dotnet Variable again (use the tab "Server")
    5.) Try executing your code again.

    Did you register your DLL when you first deploy it? If so, try unregistering it.

    No, the dll is not com enabled. I just added the dll to "C:\Program Files (x86)\Microsoft Dynamics NAV\90\RoleTailored Client\Add-ins" and connected to this dll from NAV2015.
    After upgrade to NAV2016, I had to remove the dll (delete the dll), and replace it with a 64-bit dll
    (see attached file).
    Problem 2
    It seems, that code compiled with a Amd64 Prcessor Architecture not will run together with NAV2016
    (it is not possible to load the dll)
