Do I need to uninstall previous version of Firefox before installing new version?

I am worrried about installing new version (3.6.13 ) since old version (3.0.15) is working o.k. Can you advise?

When you install a release version of Firefox (current version is 3.6.15), it will by default replace the existing version. There is no need to uninstall the old version first.

Do you need to uninstall Adobe Photoshop Elements 11 before installing Elements 12?

Is it best to uninstall Adobe Photoshop Elements 11 before installing Elements 12 or not?
If so, how do you save and transfer all Albums, Folders and Tags?
If not, do they transfer automatically?
Thanks,

Can i download previous versions of firefox? the new version does not allow me to use my VPN so i have had to uninstall firefox and use internet explorer instead (ugh!)

after i downloaded firefox 4.o.1 i have no longer been able to use my VPN which i need frequently for work. it worked fine with the previous version of firefox.

Can you describe in a little more detail which part isn't working? For example, is the VPN not starting up when you start Firefox, or is Firefox not able to use the VPN tunnel?
If we can't solve it, here's the process to roll back:
First, I recommend backing up your Firefox settings in case something goes wrong. See [https://support.mozilla.com/en-US/kb/Backing+up+your+information Backing up your information]. (You can copy your entire Firefox profile folder somewhere outside of the Mozilla folder.)
Next, download and save Firefox 3.6 to your desktop for future installation. http://www.mozilla.com/firefox/all-older
You could install Firefox 3.6 over Firefox 4 (many have reported success) or you could uninstall Firefox first. If you uninstall, do not remove your personal data and settings, just the program.
Unless you have installed an incompatible add-on, Firefox 3.6 should pick up where you left off. If there are serious issues, please post back with details.
Note: I haven't actually tried this myself!

I was unaware that I needed to uninstall the older Acrobat Reader before installing the newwer XI. Am I now able to go back and delete both versions then reinstall the XI?

I have Windows 7, and an older Abode Reader, I've just installed the newer Adobe Reader XI, but did not uninstall the older Adobe Reader. Is it too late to uninstall both versions of Adobe Readers, then reinstall the Adobe Reader XI?

If you upgrade from one Reader version to the next (e.g. Reader X to XI) it is usually not necessary to uninstall the previous version.
If you skip several versions (e.g. Reader 8 to Reader XI) it is recommended to uninstall the old version first.
My recommendation for now:
uninstall both versions using http://labs.adobe.com/downloads/acrobatcleaner.html
reinstall the latest Reader from http://get.adobe.com/reader/enterprise/

Firefox previously worked fine but after installing new version does not open. Opens in the same day that I install it but not after restarting computer.

I just installed the new version of firefox. My firefox worked fine with the previous version. But the new version only works on the day I install it but the next time i start my computer it does not work. It does not open after clicking the icon. I even uninstalled it and then reinstalled it but again the same thing happened. I have no idea about plug ins etc. but I did not install any new ones.

This is a very interesting issue. Let's start with trying [[safe mode]], [[managing profiles|new profile]], and [http://firefox.com/all-older.html installing an older version] - if one of these works, please don't do the rest and reply here.

Do I need to remove the older version of firefox before installing a new version? If so, then how much do I remove, and how?

I have an older version of Firefox and adobe on a Sony VAIO. I keep getting pop-ups telling me to upgrade, and also frequent failures when I try to use the browser. I try to upgrade. I go thru the download step, then try the run step and get a message "not allowed". I have checked and I have admin privileges, and I've turned off the firewall security software thinking that it's blocking the install, but nothing works. Does anyone know if the older software is causing this and does it need to be removed before the latest version can go on. Also, if this problem is resolved am I going to have the same problem with Adobe?

What Firefox version is currently installed on the computer?
You can find the full version of the current current Firefox release (37.0.2) in all languages and all operating systems here:
*https://www.mozilla.org/en-US/firefox/all/
If you have a very old Firefox version then you could consider to uninstall that version to clean up existing registry keys (especial the uninstall key).
Make sure NOT to remove "personal data" when you uninstall Firefox, because that will remove all profile folders and you lose personal data like bookmarks and passwords including data in profiles created by other Firefox versions.
Check the Firefox program folder and remove the Firefox program folder if there are still files left in it.
*(32 bit Windows) "C:\Program Files\Mozilla Firefox\"
*(64 bit Windows) "C:\Program Files (x86)\Mozilla Firefox\"
It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
*http://kb.mozillazine.org/Uninstalling_Firefox
Your bookmarks and other personal data are stored in the Firefox profile folder and won't be affected by an uninstall and (re)install, but make sure NOT to remove personal data when you uninstall Firefox as that will remove all Firefox profile folders and you lose your personal data.

Do I need to uninstall the Photoshop CS6 trial before installing Design & Web Premium?

I'm studying game design and my school provides a full license for Photoshop CS6. Before they provide the license they require you to install the software and use the 30 day trial, so that's what I did - I just installed the Photoshop CS6 standalone version (the full thing, not Elements). Now that my trial period has expired I've been given the license, but it seems it's for the whole Creative Suite 6 Design & Web Premium, not just Photoshop.
Should I uninstall Photoshop standalone before installing the whole Design & Web Premium suite? Or will it be okay if I go through the installation of the suite and just deselect Photoshop from the installation options? Is there any difference between the version that's installed on its own and the version that comes with the Design Premium suite? Will it affect any functionality in terms of transferring stuff between applications?
I'm running Windows 7.
Thanks in advance.

Only if you want to or need the space... versions are independent... some people have several versions installed for testing different capabilities

Do you uninstall old verison before installing new Version of Java

I have read on Suns website you should keep older versions installed due to some pages will need it to view properly. I have read many different opinions some say keep them installed and others say remove them.
What is the right answer?
This is my current version from the Console Screen
Java(TM) Plug-in: Version 1.4.2_01
Using JRE version 1.4.2_01 Java HotSpot(TM) Client VM
This information is from the about screen
Java 2 platform standard edition
Version 1.4.2_01 (build 1.4.2_01-b06)
I have Windows XP Media Center 2005 Edition (SP2) Intel P4 3.4 GHz, 2GB ram
Please advise

I keep most of my installations, but it's enough to keep one of each major version. I.e one 1.4, one 1.5, and so on.

Can I load the older version of Firefox? The new version does not work with my company's software. Need prior to 3.6.24

We have some old Ariba software and later versions of the browsers make it impossible to complete the process.
Just wondering if I can download the older version of Firefox, one prior to 3.6.24.

Use the Mozilla FTP: ftp://ftp.mozilla.org/pub/firefox/releases/

How do I get back my older version of Firefox? The new version sux.

I loved the older version of Firefox. I also had a Yahoo toolbar, a MyYearbook tool bar and a Stumble Upon extension. When I "upgraded" to the new 4.0 Beta version, all of those disappeared.
I got a notice that said the new version of Firefox is not compatible.
If it's not compatible, then I don't want it, but I seem to be stuck with it. How do I get my older version back again??

If you resaved the file and changed its name it is wherever you saved it to.
If you changed the name of the open file then that is your only copy.
You can go back to previous versions by various methods. In Pages 5 it is:
Menu > File > Revert

How can I revert to the earlier version of Firefox? This new version has me completely bewildered. I can't find ANYTHING!!!

I functioned extremely efficiently with Firefox for years. Now, suddenly the new version lacks the conveniently accessible functions to which I have become accustomed. I would like to re-install the earlier version so that I can resume my customary productivity, but I can't find the earlier version to "update" to ("downdate?") Please help me because I don't want to resort to one of the other browsers, but may have to if I can no longer figure out how to use Firefox. Nothing seems to work the way your instructions specify. You are making me feel like a gibbering idiot.

Make Firefox 4/5 look like Firefox 3.6.x:
*NOTE: Support for Firefox 3.6.x is scheduled to end soon, so we can help you find solutions for using Firefox 5.
**Also Firefox 4 support has ended (replaced by Firefox 5) and Firefox 6 is scheduled for release next week

Uninstall previous versions of Java before applying new version?

Hi,
I would like to push out java version 8.0.3.1 to some clients but I would like to uninstall any previous versions before doing so. Is this possible to do so? Maybe using supersendence? I am not sure what the best way to do this if anyone has any suggestions?
TIA

Should remove 25,
You could even stick it in a script and have it run before
your script installs 31.
This way the old would be removed and the new installed
in one deployment.

Need former version of Firefox. The new Version 4 does not work with my Kaspersky Passwd Manager. How do I download previous version?

Can't remove old version ... for install new version

I can't install the update of iTunes beacause it ends with an error in Quick Time:
Die alte Version von Quick Time kann nicht entfernt werden. Setzen Sie sich bitte mit dem technischen Support in Verbindung.
Than I tried it with "Systemsteuerung" and "Software". I doesn't work:
Fehler bei der Übernahme der Transformationspakete. Stellen sie sicher, dass die Transformationspakete gültig sind.
"

First, head into your Add/Remove programs and uninstall your QuickTime. If it goes, good. If it doesn't, we'll just attend to it when we attend to iTunes.
Next, download and install the Windows Installer CleanUp utility:
Description of the Windows Installer CleanUp Utility
Now launch Windows Installer CleanUp ("Start > All Programs > Windows Install Clean Up"), find any iTunes and/or QuickTime entries in the list of programs in CleanUp, select those entries, and click “remove”.
Next, we'll manually remove any leftover iTunes or QuickTime program files:
(1) Open Local Disk (C:) in Computer or whichever disk programs are installed on.
(2) Open the Program Files folder.
(3) Right-click the iTunes folder and select Delete and choose Yes when asked to confirm the deletion.
(4) Right-click the QuickTime folder and select Delete and choose Yes when asked to confirm the deletion. (Note: This folder may have already been deleted if QuickTime was successfully removed using Add/Remove Programs earlier.)
(5) Delete the QuickTime and QuicktimeVR files located in the C:\Windows\system32\ folder. Click Continue if Windows needs confirmation or permission to continue. (Note: These files may have already been deleted if QuickTime was successfully removed using Add/Remove Programs earlier.)
(6) Right-click on the Recycle Bin and on the shortcut menu, click Empty Recycle Bin.
(7) Restart your computer.
Now try another iTunes install. Does it go through properly now?
(thank you very much, {b nior})

A game that used to load in old browser does not load in Firefox, despite installing new version of the Adobe Flash player as instructed?

I used to have Internet Explorer as the browser on my laptop but had loads of problems. I installed Firefox as I had been told that it was more efficient. I play several application games within Facebook and one of them - Treasure Island Adventure Game - does not load whatsoever. It states if game does not load within 10 seconds to upgrade my version of the Adobe Flash player. I did that and re-started my laptop and the problem was not solved. I even deleted the application then loaded it up but it still did not make any difference.
