Hello to all and a happy new year

I have a rig with 5 RX580 8gb i use the 4 of them because when i connect the 5th it doesn't play at all.
When i pull out the fifth (any card as fifth) play with 30Mh/s
But i have the below warning :

"Unable to load EIO.dll - AMD Straps won't be available
You have to run Phoenix.exe as Administrator or IOMap64.sys is missing"

When choose Run as Administrator and execute the miner .bat it stops and with the message unknown internal command and pause

I don't know how to post image to show the exact message

Any help please ?

Thanks
