I am trying to install the lated version of Plex server on my QNAP NAS62F478 running the latest firmware.

Every time I try to do a manual install I get:
Error 2023-04-09 17:40:04 192.168.x.200 Web Desktop App Center App Installation [App Center] Failed to install Plex Media Server 1.32.0. The installation package is incompatible. Use the compatible package.

The package is downloaded complete from Plex directly.
Can anyone help please.

Which model QNAP do you have ?

(NAS62F478 is its name , based on the internal serial number)

4

Sorry its : TS-453E

All the TS-453’s are Intel CPUs.

Intel® Celeron® J6412 4-core/4-thread processor, burst up to 2.6 GHz

You want the Intel 64-bit
