Hi AK, Here are the answers to your questions: 1. The execution target you choose depends on where you want the VI's to run. If you want them to execute on your computer, then choose Windows as your target, and if you want the VI's to execute on the PDA, then chose that as the target. More informtion about this is available in chapter 4: "Building PDA VIs" in the manual that you found and linked to this post.
2. There is no workaround for these VI's. They are not supported by LV PDA mostly due to the hardware limitations of processing on a PDA. 3. LabVIEW PDA is only compatible with LV Express, version 7.0 and higher. Thanks for contacting NI! Marcus G. National Instruments
