We need to know more about your development environment...
Which DBPro version are you using... Which IDE... Which version of the plugin and whether it is the free one or paid... (as they may differ)
Which IDE you are using... (the interface in which you code with DBPro... Default or third party such as indigo...)
And how you have packaged your end product... Are you using EXE or MEDIA or INSTALLER... Are you including all objects... Did you copy all files as they are required? Is your development environment set up correctly?
Lots of questions... Hope that is ok with you... There are more... Of course
