I have added all my database n made an exe of my project in the vb.net, after instaling it in a pc problem ?

I'm guessing it has to do with the security feature. Since it's not recognized by the home Pc on which this was created. I'm pretty sure what I said makes no sense, but It probably is the reason. I'm going to guess that it's just because the program doesn't recognize the pc. I'd say don't use any security features.
