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.

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.

I updated my OS from 10.6.4., to 10.8.2 I want to buy iDVD and I Movie, but bought iPhoto and can't get it to work yet. Hesistant to buy the others without now having the original applications on my laptop. Do I need to buy the older versions first?

I updated my OS from 10.6.4., to 10.8.2. I want to buy iDVD and iMovie, but I bought iPhoto and can't get it to work yet. I'm hesitant to buy the others without now having the original applications on my laptop. Do I need to buy the older versions first? They are probably on my Snow Leopard install disc, but I am now running Mt Lion that I bought, and downloaded a few days ago...so I don't want to insert the old OS disc, thinking it might want to reinstall the old OS... Thanks,

Download iPhoto Library Manager and use its rebuild function. (In Library Manager it's the FIle -> Rebuild command)
This will create an entirely new library. It will then copy (or try to) your photos and all the associated metadata and versions to this new Library, and arrange it as close as it can to what you had in the damaged Library. It does this based on information it finds in the iPhoto sharing mechanism - but that means that things not shared won't be there, so no slideshows, books or calendars, for instance - but it should get all your events, albums and keywords, faces and places back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one.

No, you don't need to.

I was on iTunes on my computer trying to drag a song from my iPhone 4 to my computer but when I connected my phone to the computer using a USB cable then it said that it couldn't connect to my phone because I need to get the later version of iTunes. How?

I have upgraded to newer version of labview, and the older versions of LavVIEW are now piling up. Can I uninstall the older versions? if yes how?

Do I have to keep all the old versions of LabVIEW as I did not uninstall the older versions, but only downloaded the latest version of labview from the website and installed it. A new version and icon is installed on my PC now. What can I do?

You asked "Do I have to keep all the old versions...". Of course not. You can do whatever you want. Each version of LabVIEW installs in its own directory, which is what allows you to keep multiple versions installed in case you need to support programs written in earlier version that cannot be upgraded yet for whatever reason. Conflicts may arise if you install older versions later than new ones and you install the libraries for the hardware interfaces like VISA and such. Older versions of these libraries sometimes cause problems with newer versions of LabVIEW.
If you do not want multiple versions, common practice is to completely uninstall the current version before installing the new one. If you have more than two versions but only want the latest, simply uninstall the older ones from the main NI installer. Depending on how old the versions are that you are uninstalling something with the new one may break so you may need to repair that installation. You may just want to simply uninstall all NI software and then just do a clean install of the latest version. That will likely be your best course of action.

I accidentally downloaded the latested version of firefox to my outdated Mac 10.3.9 and lost the older version of firefox. I need to get the older version of firefox back?

firefox won't open on my computer as it says that it might be damaged. I downloaded the latest version of firefox and realized after the fact that the latest version is only compatible to mac 10.4 or higher. My computer is only 10.3.9 so it seems that it's too old. I tried downloading an older version from your website and it failed. Please help. I hope I don't have to go out and purchase a new computer!!

Firefox 2.0.0.20 is the last release that runs on Mac OS X 10.2 and 10.3

Firefox 4 requires at least OS X 10.5 and an Intel Mac.

I need to reinstall the older version of Firefox since 4 doesn't work with my laptop - where is it?

I updated to 4 but now it won't open. The install replaced my older version of Firefox. I can't figure out how to uninstall 4; and will that make my older version available again? If not, is it available for download on the Mozilla website?

There is a third party version of Firefox 4 that runs on OS X 10.4/10.5 and PPC Macs, for details see http://www.floodgap.com/software/tenfourfox
If you prefer, you can get the latest version of Firefox 3.6 from http://www.mozilla.com/en-US/firefox/all-older.html

HT1926 I have gone through the sequence of uninstalling and deleting everything in order as stated, but when I try to install the newer version and it gets to the part where it needs to uninstall the older version it says it can't find the iTunes msi?

Should I reinstall 10.5? Will it reinstall?

(1) Download the Windows Installer CleanUp utility installer file (msicuu2.exe) from the following Major Geeks page (use one of the links under the "DOWNLOAD LOCATIONS" thingy on the Major Geeks page):
http://majorgeeks.com/download.php?det=4459
(2) Doubleclick the msicuu2.exe file and follow the prompts to install the Windows Installer CleanUp utility. (If you're on a Windows Vista or Windows 7 system and you get a Code 800A0046 error message when doubleclicking the msicuu2.exe file, try instead right-clicking on the msicuu2.exe file and selecting "Run as administrator".)
(3) In your Start menu click All Programs and then click Windows Install Clean Up. The Windows Installer CleanUp utility window appears, listing software that is currently installed on your computer.
(4) In the list of programs that appears in CleanUp, select any iTunes entries and click "Remove", as per the following screenshot:
(5) Quit out of CleanUp, restart the PC and try another iTunes install. Does it go through properly this time?

I need to install Mozella Firefox 2.0 to fill out a form that is not supported to input info from the newer version that is installed on my PC. Do I need to delete the newer version before using the older version? If so, how do I delete the new version and install the older version?

If you just need it for one site you can use the portable version of Firefox 2 instead. You can install the portable version on a USB key, or if one is not available choose the custom install and install it somewhere on your hard drive. The portable version will not interfere with your current version of Firefox. You can get the portable version from http://portableapps.com/apps/internet/firefox_portable - the link for Firefox 2.0.0.20 is near the bottom of that page.

If i install adobe reader x or xi, do i have to delete the older version?

It should remove it for you unless you are on a Mac. If that's the case, you do not NEED to uninstall the older version but there really isn't any reason to keep it.

The older version of itunes cannot be removed. contact your technical support group.

need help with itunes 12.1
my itunes was working just fine on my windows 7 pro PC.
Update 12.1 popped up and I clicked download and install and now all of my itunes is gone.
I uninstalled all Apple software packages, and also pain stakingly went thru my registry line by line and deleted all references to itunes, apple, quicktime, etc., then downloaded fresh downloads of the installer and each time I get just about to the end of the installer and a window pops up and says
"the older version of itunes cannot be removed. contact your technical support.
So, I tried downloading the previous version 11.4 and 10.7 64bit installers and then the system won't even get started doing an install when the system responds...
"a newer version of itunes is already installed", and the installer quits.
I have cleaned my registry now about 5 times, I ran all of the apps to clean my PC of all of the apple and itune files. I am an administrator on my PC. I also went as far as creating a second administrator and switching under that account and still get the same responses.
I have removed any attached external drives and tried the installer.
I have tried to install itunes under a different folder location instead of the default C:\Program Files directory.
I have tried to install via the Apple Software Upgrade utility as well as direct downloads of the installers.
All of my music is gone.
When I run the installer now, all of the other apple software files install ok, with the exception of itunes. It gets nearly complete when the "older version" error comes up then I notice it backs off the installation and no files or directories are created.
There is nothing in the Control Panel 'Add/Remove Programs' as far as iTunes, their are no directories or files, yet it still sees a old version of itunes referenced in some file on the pc.
I ran a couple of utilities such as CCleaner, Everything, Revo Uninstaller and Registry Reviver, as well as going thru regedit line by line for hours to remove references to apple and itunes - all still with the same results.
Either I get a 'the older version cannot be removed' or 'a newer version of itunes is already installed'
very frustrated.
anyone have a installer that will complete ignoring any errors?

For general advice see Troubleshooting issues with iTunes for Windows updates.
The steps in the second box are a guide to removing everything related to iTunes and then rebuilding it which is often a good starting point unless the symptoms indicate a more specific approach. Review the other boxes and the list of support documents further down the page in case one of them applies.
Your library should be unaffected by these steps but there is backup and recovery advice elsewhere in the user tip.
If you are running 64-bit Windows and the above steps haven't helped try installing the version of iTunes that can be downloaded from this support document. iTunes 12.1 for Windows (64-bit — for older video cards)
If you still have no luck try reinstalling iTunes 12.0, links in the user tip.

Walk us through what happened with CleanUp, Michelle. In particular, was there no entry for QuickTime in the list of programs in CleanUp?
