First restore the backup you made prior to replacing your operating system, then redownload Lion and install.

How to remove and reinstall dashboard

My dashboard is not working properly. Each time I try to use dashboard it opens a web page in Safari, thus leaving the dashboard and making it impossible to use my widgets. Is there any way to fix this? Is it possible to remove the widget application and reinstalling it again, from scratch? Where could I download the dashboard application itself, so that I am able to reinstall after removing it?

Back up all data.
Triple-click the line below to select it:
~/Library/Preferences/com.apple.dashboard.plist
Right-click or control-click the highlighted line and select
Services ▹ Reveal
from the contextual menu.* A folder should open with an item selected. Move the selected item to the Desktop, leaving the window open. Log out, log in, and test. If there's no change, put the item you moved back where it was, overwriting the one that may have been created in its place. Otherwise, delete the item you moved.
*If you don't see the contextual menu item, copy the selected text to the Clipboard (command-C). In the Finder, select
Go ▹ Go to Folder...
from the menu bar, paste into the box that opens (command-V). You won't see what you pasted because a line break is included. Press return.

How to remove and reinstall PSE 10?

I am unable to edit PSE 10 to completion. The editing works fine until I try to close it. It doesn't finish and I get an error message "failed to import" (to Organizer) with a bar chart showing 95% completion. In effect, I can't edit. One other oddity that surfaced and may(?) be related is that when I try to open PSE, it opens the Editor. I can then open the Organizer from the Editor, but that's not the way things should work. I've had wonderful Adobe community help, but the problem persists. I'm well past my knowlege, and I suspect (but am not certain) I need to remove and replace my current PSE 10. I do not have a disc as I downloaded the original. How do I proceed? Thanks in advance ... Phillip Young.

Hi Phillip,
Please download Photoshop Elements 10 from the below mentioned link

Please ensure to follow the (Very Important Instructions) carefully.

HT201628 How to remove and reinstall the Apple Mobile Device Spport on Windows

my new iphone 5s cannot be recognized by itune
I installed the newest version of itune
The itune asked me to uninstall the apple mobile device support and intue
because i need newer version of apple mobile device support
I tried to uninstall the apple mobile device support
but it still in the list of my programs and features
Is there some other way to uninstall the apple mobile device support?
thanks a lot

Thanks, Tiinsky. I followed your instructions (deleting the Apple Mobile Device Support folder under C:) \Program FIles\Common Files\Apple and this seems to have done the trick.
Incidentally, even after doing so, I was still unable to uninstall Apple Mobile Device Support through the control panel. It would go three-quarters of the way through the process and then roll back the whole uninstallation.
However, removing those folders did allow me to successfully re-install iTunes--something I hadn't been able to do before. Previously, it would stall out and give me an error message reading "Service 'Apple Mobile Device' failed to start. Verify that you have sufficient privileges to start system services" with the choices Retry Abort Ignore--none of which worked.
My operating system is Vista.

Trackpad issues, told to remove and reinstall OS, how do I do that?

The next step is to remove and reinstall the OS, how do I go about doing that? If that doesn't work then it'll be replacement. Currently using the 10.7.5

Welcome to Apple Support Communities

How do I remove and reinstall Mail under iOS?

My Mail program with both my iPad 2 and my iPhone 4S keeps growing constantly in size. My iPad Mail is now at 1.7 GB. ALL messages are deleted, trash is deleted, etc. The program just isn't reclaiming storage after deletions.
I filed a bug with Apple as an Apple Developer but, after about 3 weeks, I got a message from Apple indicating that the bug had been removed because it was a duplicate. In other words, other people also have this problem (it is possible that ALL people may not have it).
Two upgrades ago, my iPad had to totally re-install from scratch (something went wrong with the upgrade). The Mail program went back to about 50 MB. As mentioned, it has now grown back to 1.7 GB (on iPad 2, only 1.4 GB on my iPhone). At this size, it is taking a significant amount of my RAM -- it was probably the reason the upgrade failed two times ago (not enough free RAM).
I need to remove my mail program and reinstall it -- or even completely refresh my iPhone/iPad. I keep hoping Apple will fix the problem but 7.1.2 still hasn't fixed it.
How do I remove and reinstall Mail (or -- at the worst -- refresh the entire iOS device (using backups from iCloud for important settings)?
Thank you. It will probably be up to 2+ GB by the end of July.

You may a bit mixed up in your terms.
RAM in an iPad/iPhone is like the RAM in your computer. It's used to run the operating system and open apps.
On the other hand, your storage space (16GB, 32GB, etc) is like the capacity of your computer's hard drive.
If you are short of storage space, look at these links.

How to Remove “Other” Data from iPhone, iPad and iPod Touch
http://www.igeeksblog.com/how-to-remove-other-data-from-iphone/
With an iOS device, the “Other” space in iTunes is used to store things like documents, settings, caches, and a few other important items. If you sync lots of documents to apps like GoodReader, DropCopy, or anything else that reads external files, your storage use can skyrocket. With iOS 5/6/7, you can see exactly which applications are taking up the most space. Just head to Settings > General > Usage, and tap the button labeled Show All Apps. The storage section will show you the app and how much storage space it is taking up. Tap on the app name to get a description of the additional storage space being used by the app’s documents and data. You can remove the storage-hogging application and all of its data directly from this screen, or manually remove the data by opening the app. Some applications, especially those designed by Apple, will allow you to remove stored data by swiping from left to right on the item to reveal a Delete button.

How to Backup your HD and Reinstall Lion

Hello to all,
I'm a Student of Informatic Engineering studiying at UCAB in Venezuela.
I have a Macbook Pro 13" late 2011 and needed of windows and ubuntu because some projects at University needed to be developed in those OS. I did the Bootcamp to add Windows to my MacBook Pro, and did an extra partition to the Macintosh HD to install the Ubuntu. All Sucess and finished the semester. Now i dont need these OS no more because i won an Acer and now i have Windows and Ubuntu in that laptop so i want my Mac only with OSX. Besides now the OSX is startint to act funny, so i think its about the triple partition (and i dont like my apps in OSX closing for no reason, and the system is getting a bit slow).
So, my question is:
1.- How do i Backup my Macintosh HD so i dont lose all my installed apps and data.
2.- Can i use Time Machine on any External Hard Drive?
3.- How do i clear all my hd so its like brand new, and Reinstall Lion (because when i bought the Mac it didnt came with an OS CD)
Thanks for any help you may bring me..
I'm Sorry for any misspelled word, English is not my main Language.
MacBook Pro 13" (Late 2011)
Specs:
Processor: Intel Core i7 2.8Ghz
Ram: 16GB 1333 Mhz DDR3
HD: 750 GB (Macintosh HD: 550 GB, Bootcamp: 160GB, Ubuntu: 40GB)
Graphics: Intel HD 3000

1.- How do i Backup my Macintosh HD so i dont lose all my installed apps and data.
2.- Can i use Time Machine on any External Hard Drive?
3.- How do i clear all my hd so its like brand new, and Reinstall Lion (because when i bought the Mac it didnt came with an OS CD)
1. Use Time Machine - it's on your Mac.
2. Yes - if the external has enough space.
3. After you back up, use the steps described in this Macworld article to make a clean install of OS X. Basically you reboot while holding down the command and R keys and proceed from there.

A 2008 Mac won't have originally shipped with Lion. You need to install 10.6.8 on the computer, log into the Mac App Store with the Apple ID you used to purchase Mountain Lion, click on the Purchases tab, and download it.

How can I format my primary HD and reinstall Lion?

So my iMac has been running very slowly lately, and I've had some tech issues (see the fruitless help thread at http://hintsforums.macworld.com/showthread.php?p=634569), so I'm tempted to just wipe my hard drive clean and reinstall Lion.
I have a backup HD, so I should have sufficient hardware to do this. I just have a couple questions about the mechanics:
1. How do I format my primary hard drive? I assume this is straightforward.
2. Is it possible to reinstall Lion without an install CD? I downloaded Lion off the App Store, and I'd hate to think that because of that I'm stuck with the installation I have.
Any advice would be appreciated. Thanks!

OS X Lion: About Lion Recovery
Summary
OS X Lion includes a new feature called Lion Recovery that includes all of the tools you need to reinstall Lion, repair your disk, and even restore from a Time Machine backup without the need for optical discs.
And buried in the link is also this:
the storage device to use the GUID partition scheme and the Mac OS Extended (Journaled) format, which are required to install Lion
Formating a disk is done with Disk Utility.

How do I get out of kernel panic? kernel panic upon boot. I did that hard drive cleanup and reinstalled Lion. What about memory? Anyone think I need to upgrade my memory? I have 8gig.

I get kernel paic upon boot. I did that hard drive cleanup and reinstalled Lion. What about memory? Anyone think I need to upgrade my memory? I have 8 G of upgraded RAM. (20 inch iMac core 2 duo)

If you're able to boot, launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ If you’re running Mac OS X 10.7 or later, open LaunchPad. Click Utilities, then Console in the page that opens.
Select the most recent panic log under System Diagnostic Reports. Post the contents — the text, please, not a screenshot. For privacy’s sake, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header and body of the report, if it’s present (it may not be.) Please don't post "shutdownStall" or "hang" reports.
If you can't boot in the usual way, try a safe boot. The instructions provided by Apple are as follows:
Be sure your Mac is shut down.
Press the power button.
Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
During startup, you’ll see a progress bar, and then the login screen, which appears even if you normally log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Safe mode is slower than normal, and some things won’t work at all.
Note: If FileVault is enabled under Mac OS X 10.7 or later, you can’t boot in safe mode.

HT1923 i have removed and reinstalled itunes at least three times and i still receive the same message, APSdaemon.exe fail to start because msvcr80.dll. i want to know how to get that file back so I can run tiunes again

I would like to know what i need to do to get the program to run again. i have not been able to locate a way to reinstall the program it says i need to have to run the program

Click here and follow the instructions. You may need to completely remove and reinstall iTunes and all related components, or run the process multiple times; this won't normally affect its library, but that should be backed up anyway.

You are referrring to how long it takes to startup your Mac?
If so, open System Preferences > General
Deselect: Restore windows when quitting and re-opening apps
And remove any apps in HD > Library > Startupitems
Make sure there's at least 15% free space on the startup disk.
Click your Apple menu icon top left in your screen. From the drop down menu click About This Mac then click More Info then select the Storage tab from the menu.
If you have anti virus software installed, disable or uninstall the software to see if that makes a difference.
