Time Machine application broken

[Liz85]

When I try to run the Time Machine application, I get an error message that the installation is corrupted or damaged. Is there anyway to download the application again or repair its installation? I no longer have an installation disk. I'm running OSX Lion 10.7.5. Thanks!

So this should be a good time to upgrade to a newer OS with a fresh TM app that works.

Hold command-r at boot to get to recovery then click reinstall OS X. That will download the OS and install it again over top of the existing install and should fix Time Machine. It will be about a 4.7GB DL.

This will not erase your data, but you should backup first just to be safe.

You need to download the OS again in this case. And may be your hard drive is corrupt, thats why it is showing this error message. So, just check the status of the drive.​
