But I have got a free version of SSD5.5
I don’t think this has anything to do with your problem, I’ve used VSTHost with a lot of free and non free VSTs.
You could also have a look on SAVIHost from the same developer. SAVIHost makes any VST plugin to be a standalone app. Unzip the file savihostXXX.zip, name it like your dll and put it in the same folder like the dll. In your case you would rename it to SSDSampler5.exe and put it beside SSDSampler5.dll. After you can create a shortcut from SSDSampler5.exe to your desktop.
