OSX Mavericks - "An Error occurred while preparing the installation. Try running this application again."

I checked and I do have the full Install OS X Mavericks.app - 5.31 GB on my HD under the Applications folder. Running a late 2011 iMAC with 12GB RAM,quad core, etc. I've downloaded the program several times, delete the old file and redownloaded and then attempted to install, but keep getting stuck at this point. Has anyone defeated this error yet?

Thanks!

iMac, Mac OS X (10.7.1)

Have you used Disk Utility to run a "Verify Disk" operation?

Bill, I've got Disk Utility opened, but what am I trying to verify? The OS X Mavericks.app or my MacIntosh HD? Sorry, I'm a relatively new user. Thanks for the quick response.

You want to verify the volume where you want to install Mavericks, which is probably Macintosh HD.

Thanks Bill. I started the verify a few minutes after you sent this message and it is still running. I don't like it though as I can't see what it is actually doing. How can I verify that it's running?

The Console utility may show messages describing the progress of the operation.

I encountered the same thing and finally figured out that the 10.8.5 update was "waiting in the queue" so to speak.

After a restart (which installed the 10.8.5 update), the mavericks installer got past the prepare error.

Thanks erlichg. I checked my computer and see that I do have the 10.8.5 update already, but I still encounter the same problem. Looks like the problem starts when the computer counts down and the ESD dmg folder opens and after a moment the folder closes and I receive the error message. Not sure what is going on.

I'm getting the exact same thing. I have tried every whichway using the installer on the same drive, a connected drive and placing the installer in different parts of the computer - Applications, desktop etc - no luck.

ChrisRR, thanks for the corroboration. It's driving me nutz...LOL. However, it successfully installed on my 2012 MBP without any hiccups. Maybe someone will find the solution. Thanks for the input. Let us know if/when you successfully update your system.

Cheers!

No worries. I'm no further on. I have this issue each time I upgrade, but I am normally able to get round it by putting the installer on a connected drive and installing the upgrade on the drive it's connected to. You might want to try that (on your own head be it) but it's not working for me this time.

I'll keep you posted in case I have a breakthrough - or a breakdown! ;-)

Having the same problem on a 2008 iMac. Was downloading, then just quit. Went back and tried to download Mavericks update again and again. Cancelled download, trashed old partially downloaded Mavericks, ran Disk Utillity, ran OnyX. Restarted many times. Just cannot get the thing updated.

I had the same issue until I simply restarted my Mac. So that is what worked for me. But I did read about more complex issues causing this error, as each situation is different.
