How can I get Java(TM) Platform SE 7 U45 10.45.2.18 back on my list of Add-ons?

Posted

Java(TM) Platform SE 7 U45 10.45.2.18 is missing from my Add-on list. I cannot find it to download. I have reinstalled Firefox, all to no avail. I have it on my laptop and Java works when I turn it on. Any suggestions for reinstalling Java(TM) Platform SE 7 U45 10.45.2.18 to my Add-on list? Can I make a copy of it off my laptop and install it on my desktop? Where is that file stored - I can't find it?

Please try running the Java test on another internet browser (not Google Chrome).

Java test didn't work on Firefox or IE. I went through everything in the Troublshooter. Still didn't work. Manually deleted all versions of Java. Rebooted the computer and reinstalled Java. Closed and Opened Firefox. Re-tesdted Java - still doesn't work.

Sometimes a problem with Firefox may be a result of malware installed on your computer, that you may not be aware of.

You can try these free programs to scan for malware, which work with your existing antivirus software:

Microsoft Security Essentials is a good permanent antivirus for Windows 7/Vista/XP if you don't already have one.


Further information can be found in the Troubleshoot Firefox issues caused by malware article.

There is a setting in the Java applet in the Windows Control Panel to prevent Java from running in your browsers. It seems unlikely this would have been turned on by accident, but if you are in a managed environment, it's possible it's an IT setting. You could check just in case.

Windows Control Panel > Java (32-bit)

(If you view your CP by category, check Programs)

Then visit the Security tab (screen shot attached).

Also, please try scanning for registry errors after you uninstall all of the Java programs. This can be done using CCleaner.

Also ensure that you remove all Java application data and the program directory from your computer's hard drive before reinstalling it.


WARNING: Removing folders/files can cause damage to other programs and the Windows operating system. use caution when manually deleting folders/files. Creating a backup of any deleted files is highly recommended!

After the re-install, I checked the Java control panel - security tab and the box to enable java on browser was un-checked (maybe default with install) Anyway, it works now. Thanks for your help, I couldn't have done it without you.
