Unable to run Plex on Synology after DSM auto update

[Peneunou]

Hi, same for me with:
DS415+ and DSM 6.2-23739 Update 2
PMS 1.13.4.5251

Unable to install the newest version PMS

Edit: It works with 64bit version, cf https://forums.plex.tv/t/synology-installation-changes-for-plex-media-server/284921
