I don't know what the "universal installer is not running" means. Does it start and then fail with an error? Does it just never start at all? What does the installerActions.log file contain?
I know there was an issue with the installer on Pentium 4 systems in 8.1.7, but I don't know of any issues with the 9i installers on any hardware. Then again, I've never heard of any installations on a cyrix CPU, so you may still have a CPU/hardware related issue.
