Unable to launch Over-the-Web Installer，Java Plug-in (Version 1.7 or higher) is missing

[TerryWang]

WIN SERVER 2012

Java JDK and JRE 8U151 installed.

Is there any setting to enable the Java plug-in of IE?

[RandyEllsworth · Accepted solution]

Install both bitwise versions of JRE. Both x86 and x64. Set system environment variables:
JAVA_HOME=C:\Program Files\Java\jre1.8.0_151
JRE_HOME=C:\Program Files (x86)\Java\jre1.8.0_151
JRE64_HOME=C:\Program Files\Java\jre1.8.0_151
Note: You don't need JDK for OTW installation nor for running an OTW 4tRAC.

Add the server name (192.168.xxx.xxx) to the Exception Site List on the Security tab in the Java Control Panel. Then reboot and try it again.

it's solved,thanks very much!

I have set the following two enviroment before:

 JAVA_HOME=C:\Program Files\Java\jdk1.8.0_151
JRE64_HOME=C:\Program Files\Java\jre1.8.0_151

and follow your instruction I install x86 jre-8u161 and set JRE_HOME,add 192.168.*.* tot he Exception Site List on the Security tab in the Java Control Panel. then,it works!
