Question Are VP 5.0 Client and VP 5.1 Host (for A Series) compatible? Answer The ViewPoint 5.1 host software (for the A Series platform) was developed and tested with the ViewPoint 5.1 client software, not the 5.0 client software. Therefore, there is a chance that unknown problems might arise if the 5.1 host software interacts with the 5.0 client software. To avoid these problems (and to save time), update the clients to ViewPoint 5.1.
