Firmware problems

[Clivefw]

I'm trying to update my R7 firmware from 1.3.1 to 1.5.0. I've downloaded the file and copied it to a formatted card but when I try to load it onto the camera I get a message saying:

Update Firmware?

1.3.1 > 1.5.0

EOSR7150.FIR

Cancel      OK   (boxes)

The trouble is the OK box is greyed out so I can't load it. Any ideas?

Did you unzip it?

mac or PC?

[Clivefw]

Yes I think so, I've got the .FIR file. PC.

ID you try selecting the greyed out OK option?

You have to use the main dial next to the shutter button to move the selection to the ok button then press the SET button as the touchscreen is not active at that stage of the firmware update.
