Could any of these apply?
Do not install the product if you use any applications, which extend standard Finder
functionality (such as Path Finder, SNAX, etc.) If you already have some of these applications,
disable them first, and then install SPSS 13 for Mac OS X. Installation may not be completed
successfully if the name of any folder in the installation path exceeds 31 characters. This is due
to a limitation of Installer VISE.
Updating or Modifying Your Installation
To add a component, start the installation program from your CD-ROM. Select any new
components that you want to include. Make sure that every option you want to include is
selected including any previously installed components.
To add an SPSS option (Categories, Conjoint, Tables, and so on), start the SPSS 13 License
Renewal utility. If your license for SPSS Base or an SPSS option has expired you should run
this utility and enter the new license(s).
An installation log file is created in the ~/Library/Logs folder of the destination volume. You
may use the information in the log file to remove the installed copy of SPSS 13 for Mac OS X.
Since you did not state what you tried, consider trying...
a) Reboot the computer and then see if SPSS 13 will run;
b) Launch Disk Utility (in Utilities folder) and repair disk permissions, then try SPSS 13;
c) If problem persists, reboot from your OS 10.5.x Install Disk, launch Disk Utility (from Utilities menu) and Repir Disk.
I'll assume you're running Java 1.4.2 or later? Might check Software Update.
Also, consider SPSS 16 as it might be more compatible with your current OS and Java 5 (J2SE 5.0).
Thanks for all your help but nothing worked. I tried all you suggested. Anyway, SPSS seems to not want to support any OSX upgrades anyway and the new versions of the software is getting more and more expensive. I think I am just going to try to use a free alternative or if I need to I'll just use the Windows version through boot camp if I absolutely have to use SPSS to run some stats.
Why not use PSPP ? It runs beautifully on Leopard and it looks and feels just like SPSS and you can run your existing SPSS files in it. The only caveat is, that if you need some of the very advanced SPSS features, you might have to wait a bit longer. But for an elementary stats course it should do fine.
This program is quite awesome. Thanks for introducing it to me. Unfortunately, it can't run MANOVA, ANCOVA or MANCOVAs. For my purporses, it could handle everything else I'd need: correlations, multiple regressions, t-tests, anovas. Maybe it will be developed. It's great I can use my existing files from SPSS as well. Thanks so much for introducing it to me. I think SPSS is just well crazy at the price they list it.
