What command are you using to generate the EXE?

Quite possibly your JSON module is not located at the same place as the other modules you are using and is not found when the EXE is generated.

If you are using Perl2Exe, you should use following option to include the modules: 

-I=dir1:dir2

[download]
where dir1 and dir2 are the directories where the modules you want to include are located.
