The invention provides a method and system for creating a single, common installation file for multiple target device types. In one approach, the method comprises providing a base engine, compiling the engine into an intermediate language code, and just-in-time compiling the intermediate code into executable code. The latter code is executed to gather the appropriate data sets and concatenate the data sets with the engine to form the installation file. The present invention also provides a method and system for utilizing the installation file to retrieve the appropriate data set(s) for the identified target device type, and to install the retrieved data set(s) onto the target device.
