Hi,
If it was installed as a Firefox extension you can try to '''Remove''' it in Firefox '''Tools''' ('''Alt''' + '''T''') > '''Add-ons''' > '''Extensions'''.

On the other hand, if it was installed as a Windows application or Internet Explorer application, you may have to uninstall it via the Windows OS Control Panel, or via the browsers concerned. The [http://answers.microsoft.com/ Windows support] would be helpful.

HT1923 I can't uninstall iTunes from the control panel on a Windows Vista machine. .

I need to uninstall iTunes so I can upgrade my Windows Vista machine to Windows 7 Home Premium. When I try to uninstall it tells me I can't because I don't have administrator privleges. I am the only user account on the machine and I have full administrator priveleges. Any idea how I can get iTunes to uninstall?

Help - I can't uninstall CS2 throught the Control Panel Add/Remove Programs in Windows XP

I recently installed a solid state drive and when I went to use CS2 it wanted me to reactivate.
I followed the instructions but was unable to reactivate.
I went to the new files to download and it told me to first uninstall my current version.
I am unable to uninstall the current version.
How do I uninstall it?

Firefox wont open and the task manager wont open as well

My firefox wont open and when i try to fix it by managing profiles, it wont start up. when i try to go through the task manager it also wont start up. i dont know what i can do to fix this. ive tried uninstalling and installing tons of times. i just dont know what to do

Clint:
Welcome to Apple Discussions.
In terms of the Firefox issue. Boot the computer and log in. Then go to Apple Menu > System Preferences > Accounts > Login Items and see if Firefox is listed there. If it is, then select it and click the minus sign at then bottom left. The reboot the computer and try to launch Firefox.
A couple of other things to check. Open a Finder Window (Commnand + N when in Finder) and look in the sidebar. Do you see a white disk-like icon named Firefox? If you do, click on it, drag the Firefox icon into the Applications folder, then eject the white disk icon.
If neither of the above work, hold down Command + Option + esc. Do you see Firefox in the list of items to Force quit? If you do, select it and Force quit.
Please let me know if any of these work.
In terms of Dashboard, do you have the install disk for the OS you have installed?

Hello Bradley,
sometimes the "opm.db file" is the culprit. In this case you should delete it.
But as much as I regret it and as strange as it may seem I fear it's a challenge for Adobe's Creative Cloud Cleaner Tool.
Sometimes - for whatever reasons - CC doesn't "want" to work. In this case you should CC completely delete and reinstall by help of Adobe Creative Cloud Cleaner Tool. (A try to uninstall by own resources is not enough!)
I quote: ... helps resolve installation problems for Adobe Creative Cloud and Adobe Creative Suite (CS3-CS6) applications. The tool removes installation records for prerelease installations of Creative Cloud or Creative Suite applications. It does not affect existing installations of previous versions of Creative Cloud or Creative Suite applications.
Please use: http://helpx.adobe.com/creative-suite/kb/cs5-cleaner-tool-installation-problems.html and follow the prescribed sequence of operations
If necessary and for further questions click through http://helpx.adobe.com/contact.html or http://helpx.adobe.com/de/contact.html and if "open" please use chat, I had the best experiences.
Good luck!

've Password job a year ago to Mobil iPhone 4, and now lost and I can not wipe data from the device or transferred to the new device .. What do I do?

iPhones require a SIM for activation.
Put the device in DFU mode (google it) and restore via iTunes.

I have photos from my computer saved on my Iphone and I can't delete them from the app photos. How can I delete them?

I have photos from my computer saved on my Iphone and I can't delete them from the app photos. How can I delete them?

You'll have to deselect the photos in the photo pane in iTunes on your computer and then sync the phone again, this will delete photos that have not been taken with the phone but synced from the computer.

I can not sign in to iCloud from the control panel on my PC

I just purchased the New iPad and decided to do the iCloud sync. I have installed the iCloud control panel to my Windows 7 Pro computer, but when I try to sign in from the control panel it doesn't log-in. I have waited for an hour to see if anything would happen and it does not. I have even tried to reinstall. Does anyone have any ideas?

I was having same issue here (using windows 7 64-bit). iCloud control panel used to work fine for me before this last update, but then it stopped letting me sign in. After entering apple id and password, just hangs with the spinning progress wheel forever..
I tried uninstalling, rebooting, and then reinstalling the control panel, but still did the same thing. I also tried changing my iCloud password; new password worked fine for signing onto icloud.com and from my iPhone 4S but still not from the control panel. The strange part was let it would let me log into it with my wife's apple id ??
That got me experimenting some more and I realized that the control panel worked fine from a different user profile on my windows computer! After experimenting and nosing around in my profiles 'AppData' folder, I managed to get it to work again:
If you have iCloud control panel log in window open, close it
Copy this path to your clipboard: C:\Users\%username%\AppData\Roaming\Apple Computer\Preferences
Goto start -> run
Paste the path and hit enter
From the folder that is opened, rename 'MobileMeAccounts.plist' out of the way (or you can delete it if want..)
Restart iCloud control panel and try logging on again. MobileMeAccounts.plist is regenerated the next time you sign out from control panel.
I'm guessing that somehow my (our) original MobileMeAccounts.plist has some sort of corruption in it, or maybe some log in attempt got hosed somehow and its preventing it from even trying? Who knows...
Hope it works out for you too!! ~~Corey

How do I uninstall Mozilla. when I try from the control panel, it doesn't do anything.

I deleted the maintenance section from the control panel section first, and now when I try to delete Mozilla, it sits there and does nothing.

Are you trying to uninstall Firefox because you are stopping using it, or to try to fix a problem?
Also, don't remove the maintenance service first, when you uninstall Firefox the maintenance service is also removed.

Quicktime wont open and is also preventing microsoft apps from opening

after doing an autoupdate to QT 7.2, there is a "shared library error" that prevents me from opening word, entourage... i have tried to fix this, but its made it worse and now the QT wont run either. is there a way that i can uninstall all the QT on my hard drive and reinstall from scratch? and will this fix the shared library problem?

Thanks baby boomer I did get the CD out.
Now, when I switch-ON my mac with the installation disc-1 (that originally came with the computer) in it, it takes me to the basic installation window. This further leads to the same issue I mentioned in my earlier post...that is when I get to the "Select a destination volume to install the Mac OS X software" screen, there's no destination listed to select. Earlier there was "Macintosh HD" but now there's nothing.
While I was exploring my options at this time, I clicked on "Disk Utility" under the "utilities" tab on top of the screen. This took me to the disk utility window that had four discs listed in the left-hand column of the window. These were: 74.5 GB TOSHIBA MK8026GAX, Macintosh HD (in light grey colour which shows that it is inactive), 4.0 GB MATSHITA DVD-R Uj-845E Media and the Mac OS X Install Disc 1.
Under the "First Aid" tab I selected 74.5 GB TOSHIBA MK8026GAX and clicked "verify". It gave an error message:"Invalid node structure. The volume Macintosh HD needs to be repaired. The underlying task reported failure on exit. 1 HFS Checked Volume needs repair."
Then I selected Macintosh HD & selected "repair" only to find the following error message:
Invaild node structure. Rebuilding Catalogue B-tree. The volume Macintosh HD could not be repaired. Error: The underlying task reported failure on exit. 1 HFS volume checked. 1 volume could not be repaired because of an error. Repair attempted on 1 volume. 1 volume could not be repaired.
The other two icons "Verify disk permissios" & "Repair disk permissions" were inactive all the time.
I even clicked on "Mount" when the "Macintosh HD" was selected. That gave the following message: "The disk Macintosh HD could not be mounted. Try running First Aid on the disk and then retry mounting."
I don't know what's happening, do you have any idea?
Please suggest something, thanks.

I tried to download a Cisco website application. The app did not download and it is stuck on the window where it has the option of open.....it will not open. The problem is that I cannot get the window off the screen and I can't get back to the App Store home page! Help! Thanks

Try this.
Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.
