HT1338 how can I reinstall the email application as well as the original applications to IMac

Question

I was moving things around and all, and every application disappeared from the "Dock". However, a "?" sing appears on every spot of where there were an application, if I run the mouse over the "?" symbol the name of an application appears on the location where it was previously posted with its Icon. I have reinstalled Moutain Lion, and the Disk. I cannot find any applications on the "application folder/tab", I can not retrieve it from an all files search, I cannot open "time capsule"

Answer 1

Double-click on your hard drive's Desktop icon. It will be shown in the Finder window that opens. If it does not then you have removed it or moved it. Search for it otherwise, you need to reinstall OS X.
Reinstalling Lion/Mountain Lion Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
Next time don't go moving things around when you don't know what you are doing.
