WinZip 12.1 installs and runs well in Crossover 9.0.
(Also confirmed that WinZip 14.0 works well with Crossover 9.0.)
Good job, Wine and Crossover developers!
This was tested using Red Hat Enterprise Linux 5.
If the Crossover 9.0 "Install Windows Software" tool appears to hang after the WinZip installer exits, wait a few seconds, then click "cancel", after which the Crossover 9.0 tool will finish the installation.
