Hi,
I'm italian too :) I wrote in english in order to allow others to understand what I wrote.
I know that there are some problems with the setup installer on Windows 64bit. I have to fix them ASAP. By now you may download the .zip version and register the dll "by hand" using gacutil. You may also decide to avoid from the registration in GAC and use the dlls in your code putting them in the working directory of your app.
Then, the current version of Virtual Cryptoki is for 32bit only. This means that if you want to use it as a virtual HSM you have to use the 32bit version of NCryptoki.
The other errors you are mentioning usually happen after more attempts to register the assembly in the GAC. Delete all NCryptoki entries in the GAC folder and use the dll in the zip.
My suggestions: delete all the NCryptoki entries in the GAC folder, uninstall the SDK and use the .zip version of the SDK. After that let me know.
Anyway, tomorrow I'll try to do the same on my Windows 7 64bit to see what happen.
