I've had a Z3200 non-postscript for a few years and never had a problem updating the firmware. I just bought a second, identical unit (they're both Q6718A's). The firmware on the recent purchase is outdated (TR12-RB_11.0.0.3).
I download the EXE file (TR12-RB_16_00_00-1_mvl40-x86-opt_B.exe), run it to unzip it, and in the web interface setup > update firmware try to point the software at the file TR12-RB_16_00_00-1_mvl40-x86-opt_B.fmw. However, that file (and every other in the unzipped download) is greyed out and the software won't allow me to select it.
I double checked that I have the correct download for the Z3200 A-series.
Any ideas?
