Cannot download to a New AB 1756-L61,Software version 15.01

I keep getting the message below when I try to download my program
to a 1756-L61 ControlLogix Controller.
"The revision of the offline project and the controller’s firmware are not compatible."
I go into the ControlFlash program and the only choices I get
are the following.
1756-L61S , 1756-L62S ,1756-LSP , 1769-L32E ,it does not continue
because it does not match.

Any Ideas,

Thanks in Advance,

If you see 1756-L61S , 1756-L62S ,1756-LSP then you have ver 14 FW set, not 15

Get ver 15.04 firmware from support site and install it.

Flash controller form the ControlFlash application.

New controller comes with no FW, so you must flash it

Its a Guard logix controller so you should use Version 14 series with controller its a seperate software. you can not use the normal RSL5k
