I am testing an installation of OBIEE on Windows 10(Pro). After installing JDK8 and database, when I tried to start the installation of FMW(Web Logic), it gave me this error.
To solve this, I copied the FMW Jar file in the Java home(C:\Program Files\Java\Jdk1.8.0_321\bin, as shown below.
After doing so, installer ran just fine.
Hope that helps.
