Step 14 – Head back into the App Center window and click OK on the Plex Media App install setup window Step 13 – Scroll down to the ‘Plex’ entry and give it Read and Write Access, then save the changes Step 12 – Then (IMPORTANT) Select the drop down menu at the top and switch to ‘System Internal’ DSM 6 7.0 migration setups), make sure that the PLEX user account still has Read and/or Read/Write Access in the tick box list Step 11 – If Plex has created a local User (likely in DSM 6.2.

Step 8 – Select the Folder that your Media is located in. Step 6 – (This is the NEW bit) Give the Plex Media Server Application Permission to access the media directories. Step 5 – Select Location of where the Log Files will be installed – Can be left blank and it will save to default directory Step 4 – Install Beta Application (speed depends on Internet Connection) Step 3 – Find Plex Media Server and select Join Beta Previously these steps might be needed by most people but were not directed by the application especially clearly, so having these steps integrated into the formal setup is actually quite a smart idea by Synology.
