Error: The installation failed. An unknown installation occurred when installing bundled applications

the date and time reset worked. but just in case, while you also on disk utility, might as well run the permissions check to get rid of all errors.

thanks for the help.

I had the same issue, and you solved it. cheers!

brilliant. set the clock back to purchase date and now installs just fine!

thanks Philbo80

You are an absolute star/genious.... but I only purchased my macbookpro a year ago (april 2011)... why would the certificate expire so soon?

Hi Clem,

Thank you, I'm glad it helped you and everyone else because I'm sure some people will have been tearing their hair out as I was! I have no idea why the certificate expires so soon, I only got my iMac in May 2011. Maybe it's to get people to buy it through the App Store, I was advised I could do this if I didn't want to wait for a new DVD!

This sounds like the problem I'm having, but I'm not sure what you mean by resetting the date on my imac. How do I do this?

In System Preferences>Date & Time, 1st uncheck Automatically Update from the Internet, then set the Date.

PHIL YOU SAVED MY NIGHT! I was about to turn CRAAAAZY!!!

HAHA THX

Thanks Guys!

Hahaha, Stupid!

This worked for me! Yay thankyou!!

I'm having the same issues but since I installed a new HD, I don't have access to my system preferences, so i cant change the date.

apple sent me a brand new snow leopard disc but I still can't install.

thoughts??

I thought the issue concerned the bundled application disk not the install DVD ... Anyhow when you start installing if you get past the select you language screen, you move you mouse towards the top of the screen ... You get a menu

I could'nt see anything that would set the date... But it does give you access to terminal ... Look at this

Hope it helps

sorry, meant to specify my issues with the install DVD.

I was able to change the date via terminal but was still not able to instal snow leopard.

off to the genius bar I go...

thanks for the link/help.

Thanks a lot for the tip! I had the same problem and I was wondering if the disc is not fine or I might need to re-install the OS but thanks to your tip i didn't have to do that! saved a lot of time. Thanks 🙂

Per Philbo80, this worked for me too: "I set the date on my iMac back to around the date I bought it and it worked fine!"
