javaws fails to launch Spectrum OneClick on multiple laptops/desktops

Products

• CA Spectrum

Issue/Introduction

When we launch OneClick, we don't get past the java web start splash screen.  We've tried reinstalling java, and we've gone through the troubleshooting faq on CA's website.  Nothing seems to help.

Environment

OneClick client machines on Windows

Cause

Java had been finding and attempting to use a dll that was recently installed by an application.  This was revealed as an error in the Windows Event Viewer.  You could also use Dependency Walker and see whether any of the dll files come from somewhere other than the Windows directory or the jre directory (don't worry about the errors opening the Windows dlls at the top):

Resolution

Uninstall the conflicting application.  Reboot.  Reinstall the JRE.
