Symptom(s) ~~~~~~~~~~ Running setup.exe from disk1 results in JVM Launcher dialog with error message: "main class could not be found, program will exit!" Cause ~~~~~~~ The Oracle Universal Installer version supplied with 184.108.40.206 RDBMS Enterprise Edition, copies the expanded OUI classes and JRE (v220.127.116.11.0a) from the distribution media (Disk1\stage\Components\oracle.swd.jre\18.104.22.168.0a) to the current user's TEMP directory as defined by : HKEY_CURRENT_USER\Environment\TEMP and/or HKEY_CURRENT_USER\Environment\TMP in the registry. This is likely to be something like : C:\Documents and Settings\
\Local Settings\Temp Then it builds a command line to invoke the JRE and start the main OUI class. This command line includes the -CP switch to JAVAW.EXE that specifies the CLASSPATH for the JRE. This CLASSPATH will contain the directory specified in HKEY_CURRENT_USER\Environment\TEMP amoungst others. If the directory specified by HKEY_CURRENT_USER\Environment\TEMP contains a hash symbol, #, then when the JVM comes to parse the dynamically built CLASSPATH it will fail and be unable to load its core classes from rt.jar - hence the error. The default directory specified by HKEY_CURRENT_USER\Environment\TEMP is : %USERPROFILE%\Local Settings\Temp %USERPROFILE% is an OS envrionment variable and will contain the OS user name. The cause was discovered when using a username with a hash symbol in it, i.e. #dba, resulting in a path like : C:\Documents and Settings\#dba\Local Settings\Temp Fix ~~~~ Change : HKEY_CURRENT_USER\Environment\TEMP and/or HKEY_CURRENT_USER\Environment\TMP to point to c:\temp or some other writable directory path with no special characters. (NOTE: Make sure the directory exists, before assigning the directory). References ~~~~~~~~~~~ Other install issues : Note:137200.1 Checklist when Oracle Universal Installer (OUI) fails for Windows
