Below are the steps I took:

1. Install Crossover:

   sudo yum localinstall http://media.codeweavers.com/pub/crossover/cxlinux/demo/crossover-14.0.3-1.rpm

2. Install all needed dependencies:

   sudo yum install fontconfig.i686 fontconfig.x86_64 lcms2.x86_64 libXcomposite.i686 libXcomposite.x86_64 libXinerama.i686 libXinerama.x86_64 libgphoto2.i686 libgphoto2.x86_64 libxml2.i686 libxml2.x86_64 libxslt.i686 libxslt.x86_64 openal-soft.i686 openal-soft.x86_64 openldap.i686 openldap.x86_64 sane-backends-libs.i686 sane-backends-libs.x86_64 mesa-dri-drivers.i686 libtxc_dxtn.i686 isdn4k-utils-devel.i686 gsm-devel.i686 gstreamer-plugins-base-devel.i686 lcms2.i686 mesa-libOSMesa-devel.i686 libtiff-devel.i686 gnutls-devel.i686

3. Further needed actions:

   sudo ln -s /usr/lib/libOSMesa.so /usr/lib/libOSMesa.so.6

   sudo ln -s /usr/lib/libtiff.so.5.2.0 /usr/lib/libtiff.so.4

/usr/lib/libhal.so.1

In recent versions of Fedora, this library is provided by hal-devel.i686, which can be found most recently in this location. It has since been outdated by udisks, upower and libudev. More information can be found at this link.

/usr/lib/libmpg123.so.0

Possibly need libmpg123-devel.i686
The above package depends upon libmpg123.i686 which does not currently exist in RPMFusion repos.
