The complete procedure for fixing the JRE on Pentium 4 problem -
Here (scroll to the bottom
Oracle stores the JRE binaries and classes in C:\Program Files\Oracle\jre\... directories. Every time you request Oracle GUI which uses JRE to be run, the JREW.exe is executed from this location. So how do you think, where should you place the *.dll ???
If you think - C:\Program Files\Oracle\jre\bin , then that's the correct answer !!!
Hope that helps,
