AGain.dll produced, can't load in Cubase 7.5

[Vstplay]

I have compiled the output for AGain.dll from Visual Studio 2012, but I am unable to load it in Cubase, however I was able to load it in this host.

Could somebody explain whats the problem?

What is the reported error? Always include the reported error

There's no error, when I put it in the folder and point Cubase to it. Nothing happens i.e. it doesn't update in the list of plugins available. Am I doing something wrong?

Because I was able to load it in the other Test Host.

Did you compile it for the correct architecture? If your host is 64-bit, the plugin needs to be 64-bit as well.

Thank you very much. It works
