Hamied,
I didn't understand exactly what you meant.
All kinds of java are installed on the computer where the setup was generated and the executable presents the mentioned error.
B4JPackager, according to Erel's tutorial, generates an executable with everything encapsulated, that is, the java is already "inside" the executable (.exe and the 4 folders: bin, conf, legal and lib).
As I said, clicking on the .exe, the program runs normally.
The installation, created by Inno, is creating the error. At least that's what it looks like.
