Please keep in mind that Java 1.7 in Version 8.00A is only supported with Servicepack 6 (or higher) if you are using a lower Version or Servicepack please upgrade to 8.00A SP6 (or higher) if you are running on Version 9.00A please check the Knowledge Base Article related to this Version.
When trying to start Utilities the Splash Screen appears for a second, and disappears without showing the program
Was the utility installation an upgrade? Did you upgrade from utilities of an earlier hotfix or servicepack?
Are you using Java 1.7? (to find this, please enter the command "java -version" into the commandline of Windows
Possible reason for the issue;
The upgrade kept the old .ini Files however when the Utilities were made ready for Java 1.7 support there have been new restrictions into the java-commands, which makes it necessary to change the .ini files.
The Upgrade copies the recent .ini Files into the utility folder and renames them to e.g. "ucybdbld.ori.ini"
Rename the old .ini File (e.g. ucybdbyld.ini) to ucybdbld.ini.old)
Take the new file, rename it to the name of the old .ini file e.g. "ucybdbld.ini" and assign the settings from the old .ini File into the new one (db connect string, and other details you had for your utilities) you can copy and paste the values from the old .ini file to the new one.
Restart the utility, it will work then
Using Java 1.6, the old .ini Files can handle this version (of course the new ones too)
Start the .bat file of the utility out of the commandline (e.g. ucybdbldg.bat) it will open the utility screen also with the old .ini files and Java 1.7
