SPSS 12 has similar problems to those reported for 11 and 11.5 - seems to be related to the software being able to access the processor?
With CX 4.1, Fedora Core 3, and SPSS 12, the install seems to go fine, but when trying to start the program, the following error message appears:
"Unable to connect to the SPSS 12.0 for Windows Processor on the local computer"
