Cannot find keycodev2.dll or invalid keycode

Hi,

I'm working on VB.Net (Window Base), I have add crystal report in my application. When I make a setup file in my own PC and I have try to run the exe file, it seem work nice on my own PC. Then I try to run the setup in other machine, and try to run the exe as well, when I open the report from it, it give me a error msg. The error msg are look like this 'Cannot find keycodev2.dll or invalid keycode.'

Can anyone teach me step by step to slove this error? Thanks.
