Java installed but not working

Hi, after updating to Java 7 update 10 Java stopped working. Plug in checker indicates Java Deployment Toolkit 7.0.100.18 is installed correctly, but Java test page says plugin needed and Java Runtime Environment 1.7 u10 is available. Install fails. Uninstalled Java and tried manual install (including as administrator) but no resolution. All old Java versions have been uninstalled. Thank you for your time.

Re: Java installed but not working

Please check if all your plugins are up-to-date. To do this, go to the Mozilla Plugin Check site.

Once you're there, the site will check if all your plugins have the latest versions. If you see plugins in the list that have a yellow Update button or a red Update now button, please update these immediately.

To do so, please click each red or yellow button. Then you should see a site that allows you to download the latest version. Double-click the downloaded file to start the installation and follow the steps mentioned in the installation procedure.

Re: Java installed but not working

The issue is not with Firefox but with a problem with the Java installer and the IsScript.msi on the user’s machine. The Java installer is updating or loading the Java Deployment Toolkit but not the Java ™ Platform SE 7 U10 plugin (you can confirm this by going to Tools => Add ons =>Add-ons Manager and see one but not the other)

1- Download the offline version of the Java installer file to your Desktop. Run the file with the command; javadownloadfile.exe /LV* %TEMP%\jreMSI.log (where javadownloadfile.exe is the name of the offline java installer file)

You will get a log file (reMSI.log) in your %Temp% file that should show one or both messages; ISSCRIPT_VERSION_MISSING = The InstallScript engine is missing from this machine. If available, please run ISScript.msi, or contact your support personnel for further assistance.

And/Or ISSCRIPT_VERSION_OLD = The InstallScript engine on this machine is older than the version required to run this setup. If available, please install the latest version of ISScript.msi, or contact your support personnel for further assistance.

2 - Go to link below to find the procedures to fix the issue for the update file you are running. http://consumerdocs.installshield.com/selfservice/viewContent.do?externalId=Q108158&sliceId=1

NOTE - If in doubt about version number for the update file just

Delete the folder C:\Program Files\Common Files\InstallShield\engine 

Run IkernelUpdate.exe found at http://consumerdocs.installshield.com/selfservice /viewContent.do?externalId=Q108158&sliceId=1

3 – Uninstall the Java version installed incorrectly by going to Control Panel => Programs and Features

4 – Re-run the javadownloadfile.exe by double clicking it from your Desk top.

5 – Confirm that Java ™ Platform SE 7 U10 plugin is now installed by going to Tools => Add ons =>Add-ons Manager

6 – Test that Java is now working thru the Java Website tester

Enjoy!

Re: Java installed but not working

I tried all the solutions here... updating InstallShield seemed promising, but didn't work for me. I found a solution that did work at http://support.mozilla.org/en-US/questions/937263?esab=a&s=Java+installed+but+not+working&r=3&as=s (editing the Windows registry MozillaPlugins subkey).

You can also check for issues caused by an installed JavaFX program.

Re: Java installed but not working

I’ve tried everything short of messing around with the registry and can’t get Java working properly with Firefox, so have resorted to using IE for Java specific sites. Thanks all for the replies.
