C# .Net version

When I try to run the DeviceInfo application I am getting the following error:

System.BadImageFormatException: 'Could not load file or assembly 'net-neurosdk-x64d, Version=1.4.1.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. An attempt was made to load a program with an incorrect format.'

Please advise.

Thanks
