A possible problem with IrfanView installation on Mountain Lion has been reported. I am moving discussion to this new thread. Here is some relevant excerpts from previous discussion:
===
Mac mini i7 8 gB RAM OS 10.8.1
CrossOver 11.2.1
I installed Irfanview433 by opening CrossOver and clicking on Install Windows Software and using Other Applications. When the window said installation complete, I clicked Done. Then I went back to the CrossOver window and clicked on 2 Run Windows Software but nothing happened. I closed CrossOver and repeated the entire process, but Run Windows software does nothing.
What am I doing wrong?

My guess is that you forgot to install "Microsoft Visual C++ 6.0 Redistributable".
There are instructions on how to install IrfanView in the Tips & Tricks
http://www.codeweavers.com/compatibility/browse/name/?app_id=268;tips=1
The easiest way to is to use CrossTie, which automatically resolves the C++ dependency.
See the 4th Tip & Trick called: "Install IrfanView via CrossTie" tip.

The Visual Basic will not install automatically as the tip says, but I tried installing it from Other Applications. It completed the installation in the window and I clicked done, but it will not run, just as the Irfan will not run. I think Crossover does not work in Mountain Lion. Can you give me an exe from the list that will confirm proper operation? I might try 7zip.
