I am developing a HMI project using FT view machine edition 6.1 in win7 64 bit operation system. The generated 6.0 run time file is to be downloaded to a PV+ 1500 6.0 version. I don't have that PV+ with me now and I am not sure if 6.1 64bit development will work on the PV+ 6.0 . Should I switch to FT view 6.0 windows 32 bit environment for development now? I would appreciate if someone could share his/her experience here.
