You can run cgacutil , which is located in the Windows folder. It should provide you with the version number of the compact frame installed on the device. You probably don't have the right compact frame.
If you do not have cgacutil, its likely that the compact structure will not be installed on the device at all. In this case, download the latest version of the framework (currently 3.5, available here ). Installation may take up about 7 MB of space from your main memory. If the storage space is hard, it can be installed in external memory with some potential consequences, as discussed here
