If users try to install pylon 5 on a PC where another pylon already installed, the new version pylon will uninstall the old version before installing. However, sue to the new "Copy Deployment"capability of pylon 5, users can just copy the needed pylon files on a system where another pylon already installed and it will work ( provided that the new pylon uses the same drivers as the old one which is the case e.g. for pylon 4.2 and pylon 5).
From the official news:
Thanks to new possibility of simple copy deployment program generated with the pylon SDK can be delivered to the end user as easy as never before. Thus, pylon can be installed without conflicts with machine vision software packages from other manufactures based on GenlCam technology:
- Up to now pylon could only be redistributed with dedicated pylon re-dist installers
- Only one pylon version could exist on the target PC
- With pylon 5, it can be redistributed by simply copying the needed files to the target PC
- Multiple versions of pylon can be installed side by side on the same system
