Not sure what the story might be w/ the .exe (which is as you noted, very PC).
I tried grabbing a random Canson profile (also on Mac but there is/was no choice)....

So what is the .oms file? From
http://www.canson-infinity.com/en/icc-profilesWhat is a "paper preset"?
A paper preset is an installable package that extends the default selection of papers pre-installed on your HP Designjet Z3200 Photo Printer.
It contains all the necessary settings and parameters to work with optimal image quality, productivity, and reliability with your added media.
The paper presets include the ICC profile and many additional settings related to the printer-ink-paper interaction, like: total ink volume, gloss enhancer volume, star wheels position, media name, etc…
Downloading and installing the preset
Download the oms file bearing the name of the printing material you wish to use. You will find thereafter installation instruction for OS X and Windows operating systems. After the installation, a new entry will be found for your paper preset on the printer’s front panel.
Steps for Macintosh users:
1. Open the HP Printer Utility application
2. Select the option Import Paper Preset inside the HP Color Center, click on Import.
