How can I downgrade my Java version and Runtime Environment to 6?

Hi, thanks for reading this in advance:
I have a couple problems. Ever since Java Preferences was removed in one of Lion's updates I have been having trouble with java.
How do I downgrade my java and runtime environment to java 6?
When I go into terminal, and type java -version, this is what I get:
java version "1.7.0_09"
Java(TM) SE Runtime Environment (build 1.7.0_09-b05)
Java HotSpot(TM) 64-Bit Server VM (build 23.5-b02, mixed mode)
How do I downgrade the "java version" to 6 and how do I downgrade the SE Runtime Environment to 6?
I accidentally installed 7 a couple days ago and I've been having trouble with some applications.
Thank you so much.

Dear Minionsman and everyone who reads this. I was so happy when i downgraded and i wanted to share it to all, I have found out why it says this in terminal
java version "1.7.0_09"
Java(TM) SE Runtime Environment (build 1.7.0_09-b05)
Java HotSpot(TM) 64-Bit Server VM (build 23.5-b02, mixed mode)
and why it says something different on java tester
Its because java 7 blocks every java version below it.
How do you downgrade?
Well all you do is delete a few files
INSTRUCTIONS BELOW
1.Open Terminal
2. Enter these commands
sudo mkdir -p /Library/Internet\ Plug-Ins/disabled
sudo mv /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin /Library/Internet\ Plug-Ins/disabled
sudo ln -sf /System/Library/Java/Support/Deploy.bundle/Contents/Resources/JavaPlugin2_NPAPI .plugin /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin
sudo ln -sf /System/Library/Frameworks/JavaVM.framework/Commands/javaws /usr/bin/javaws
3.
Go to /Library/Internet Plug-Ins/ and delete the JavaAppletPlugin.plugin bundle.
4.
Go to /System/Library/Java/JavaVirtualMachines/ and delete anything whose name starts with jdk1.7.0 or says Java 7 or something similar.
5. now go to terminal and type
java -version
6.it should say something like this
java version "1.6.0_35"
Java(TM) SE Runtime Environment (build 1.6.0_35-b10-428-11M4508)
Java HotSpot(TM) 64-Bit Server VM (build 20.10-b01-428, mixed mode)

Version 10 doesn't work with a web site I use constantly. How can I download a lower version and have the app appear on my phone?

Have been using a lower version of firefox on my samsung galaxy phone to access [email protected] for quite some time. Since the upgrade to 10.0, I receive a server error everytime I try to access. Want to download a lower version, but app doesn't appear on my phone. How can I download a lower version and get the app to show up on my phone?

Mandel is referring to what is called a "User Agent Faker' which tricks the website into thinking it is a different browser or version than it actually is. I sometimes would use this on my iPhone when I wanted to visit the full website of a site I was attempting to go to & it would only take me to the mobile version or state it was only compatible with say Internet Explorer, simply turn it on & select the browser and details you want it to report and it will spoof that browser & you'll be on your way.

How can I downgrade from 11.0 and re-install 10.7

How can I downgrade from 11.0 and re-install 10.7

First, reconsider your decision. 11.x isn't quite as user-friendly as 10.x, but it has pretty much the same functions are before (albeit in different places). Give it a few more days, and you might grow to like it. Future releases will only get better.

How can I Downgrade to Snow Leopard and keeping all 3rd party apps?

New to MacBookPro and really happy. With Lion...not so much. I want to downgrade to SL, however, apparently I must reformat the hard drive. Here´s the real question: If I have a backup of my entire HD with the user, docs and all the apps I have installed (on Lion), once I downgrade to Snow Leopard, can I just move all my apps from the back up disk I have made of my Lion-Running hard drive? In other words, How can I downgrade without having to reinstall every single third party app I have?

First, how new is this Mac? A Mac as a rule cannot boot to an older operating system version than that with which it was originally supplied. In other words, if this is a new MBP that came with Lion then you probably cannot get it to boot to SL.
Some applications (and I take it you do mean full "applications" rather than "apps" which are mobile device programs -- it helps to be clear o terminology) can just be dragged from place to place. Others, notably Adobe and Office, install things all over the place and unless you are good at finding hidden files with obscure names in 10 different places you will just have to re-install them.

Flickr doesn't work in this version - How can I Downgrade to a version that flikr works?

Many of the buttons on the Site Flickr don't work in this version - How do is Downgrade Firefox to an earlier version so I can use flickr. -
The buttons work fine with the same account on other browsers. They worked fine in the earlier version. I trashed Firefox and reinstalled it - I installed Firefox 4.0 beta - both had no effect.
The buttons that don't work are the "action" buttons - the "share" button - the left and right arrow buttons on either side of the row of 5 preview pictures.
I am running Firefox on a mac powerbook G4 - lots of memory,

hello, although it is meant mainly for enterprise use, for the moment you could still use the firefox 17esr release which will receive security updates for another one or two months: https://www.mozilla.org/en-US/firefox/organizations/all.html (scroll down into the second part of the page)
just as a general pointer: i wouldn't trust a bank very much when it forces you to use outdated and vulnerable browser for such a sensible task like online-banking...

Just bought an Imac G5 but can't do much with it, how can I upgrade to neewer version and which is the next version after 10.4.11?

HI, I just bought an Imac G5 with 10.4.11 OS in it but I can't do much with it. I can't even wach Netflix on it because it needs a newer version of browser but I can't download newer version because My Mac's OS is to old, at least 10.6 needed. Can anybody can help Me? Thank you

No, sorry. It was only ever available on Disc. You can search places like eBay or Amazon for a Retail Copy. Do not get the Grey Set as they are machine specific. I don't think 10.5 will let you do much more than 10.4 as you said you needed at least 10.6 which is not possible due to the age of your Mac.
Cheers
Pete

How can I downgrade back to Firefox 3.6 because 4.0 won't run on my version of OSX?

I downloaded Firefox 4.0 & installed it on my MacBook running OSX.4.11 but when I tried to run it I got an error saying it was not compatible with my version of OSX.
So if I can't open Firefox I lose all my bookmarks....
How can I downgrade to the version I was running before I upgraded & replaced all the files with version 4? I think this was 3.6 as I do upgrade regularly.
Thanks!

You can get the latest version of Firefox 3.6 from http://www.mozilla.com/en-US/firefox/all-older.html
When you re-install Firefox 3.6 it will use your existing bookmarks, passwords and other user data.
Mozilla are working to prevent Mac users with non-compatible systems from getting the notification about Firefox 4, and also not displaying the "Download Firefox 4" button on http://www.mozilla.com

This is a copy of ONEof the keys in the registry I changed as told by Apple support today. I also have changed others as instructed by GEAR software support to manually delete GEAR drivers (that I had installed but couldn't delete some of the others they mentioned from Windows system 32. Then some bright spark at work told me I need the Gear drivers so I downloaded the software and installed again.
Sorry, just this minute went to insert image and it is giving me a message saying this sort of content is not allowed?.
The most recent key I altered is in: HKey _local _machine. System\class - 4D36E965-E325-11CEBFC1-08002BE10318. Upper Filter data: Upper filter NTIDrvr SiRem GEARAspiWDN.
The GEARsoftware info about manually deleting GEAR drive is from:

I hope you can help

How can I downgrade to a previous version?

How can I downgrade to a previous version. I upgraded to 2.3 and now my site is totally hosed because the fonts on the master page are changing size arbitrarily without me touching them. I've had to eliminate my site map on the bottom of my master page because I've spent over 20 hours trying to correct the issue and can't seem to get anywhere. Even completely recreating the page doesn't correct the problem.
I was going to simply change a few photos from an older backup copy of the html files, but when I opened them with the 2.3 version, it changed all of the font sized on those files too.
I need my site working properly, so, how can I downgrade to the previous version and get my site working again until the bug is fixed?
Help please!

Downgrading isn't supported and wouldn't help. You need to fix your phone.
1. Delete and reinstall all email accounts.
2, Restore the phone in iTunes, first using a backup and if needed as a new phone.

Can you restore from backup? That would be best to keep all your stuff. You can find usually several versions under restore option in iTunes. I really hope you have one of those iOS7 versions backed up to iTunes.
If you really want to start over, and I mean no contacts, photos, music, apps, anything but factory settings that aren't in the cloud or in one of the restore options. You can search ios 7.1.2 firmware and download it and install by shift click restore and choose the file you downloaded. But that is a really desperate act. But this also requires iTunes and if you've been using iTunes you probably have a backup.

After upgrading to version 6 my ArcGIS files become corrupted if I save them while I have FF open (sporadic occurence, but limited to FF being open). How can I downgrade to version 5?

I am using ArcGIS 10 and Firefox 6 on Windows XP.
After upgrading to version 6 my ArcGIS files become corrupted if I save them while I have FF open (sporadic occurence, but limited to FF being open). Any ideas of what could be causing this? I have also posted on the ArcGIS forum site for input from that side.
How can I downgrade to version 5? If that is the only option available.

Thanks for the reply. It doesn't have to process the php, it just has to show the HTML content. It did that just fine before the last upgrade but won't now.
I've seen that page you referenced: http://kb.mozillazine.org/File_types_and_download_actions.
It doesn't help. The things it says to look for aren't there for me, specifically:
browser.download.pluginOverrideTypes
plugin.disable_full_page_plugin_for_types
I followed the rest of the instructions but it didn't help.
I did get it to quit opening tabs, instead it prompts me what it should do with the file every time now. What it should do, and used to do, is open the php page and display the HTML content.
Any other ideas?

MattiP is right, I tested it, and the problem seems to occur only if there are special characters used in the filename (which was no problem with the previous version of the Adobe Reader for WP7); unfortunately, having special characters in the filename is very likely in German ...
