Oracle Universal Installer

—————————

The Java RunTime Environment was not found at C:\DOCUME~1\v859971\LOCALS~1\Temp\OraInstall2013-09-05_01-10-08PM\jre\bin\javaw.exe. Hence, the Oracle Universal Installer cannot be run.

Please visit http://www.javasoft.com and install JRE version 1.3.1 or higher and try again.

A Discussion about the same here:

Here is a quick workaround to address such situations

Copy the latest jre installation to a path without spaces

to, eg: C:\jre6

Switch to the folder where you have the “setup.exe”

C:\WINDOWS\system32>d:

D:\>cd D:\WebLogic\Middleware\oracle_common\oui\bin

Check what are the switches supported by the “setup.exe”

D:\WebLogic\Middleware\oracle_common\oui\bin>setup.exe -jreLoc C:\jre6 –help

Now, start uninstall process by starting the “setup.exe” with required switches

D:\WebLogic\Middleware\oracle_common\oui\bin>setup.exe -jreLoc C:\jre6 –deinstall

The setup GUI should start without throwing further errors now!

Once the components are uninstalled, you can uninstall weblogic server from “Oracle Weblogic” context menu, and the operation(s) should be smooth!
