I just followed the instructional video on Codeweavers site to install CrossOver and then a Windows application, having already downloaded the Irfanview .exe file to my Chromebook. I pointed the installation to my downloaded file and it installed. If you decide to leave the check box checked, to run Irfanview after the install, the installation in CrossOver will not complete until you close Irfanview. I only tested file load, save, and picture crop, all of which worked without a hitch.
