Itunes 11.1.1 Errors occurred during installation...

This is not working. I get the same problem/error from the Apple Update Utility or from downloading it from the apple.com site and running the install myself. Errors out as it attempts to verify the last part of ITues installation. You have a bad build. Please rebuild and re-release..

Also, the Apple Update Utility corrupted my previous iTunes, so nothing works!

Dude's why worries !! i found a Solution

1) Download QuickTime http://support.apple.com/kb/DL837 and install this !!

2) Install your official itune setup !!..

enjoy 😀 miffy

Had this issue, and none of the solutions above worked, here is what I did to fix the issue, Install Itunes like you normally would, admin rights ect. When you get the error message "Itunes errors occurred during installation before itunes could be configured" do not click finish, leave that folder up, no navigate to your appdata directory such as example C:\Users\Your Username\appdata\local\temp, inside there look for a file called iTunes64Setup.log or iTunes32Setup1850.log, open that up and scroll down, look for these key things as in example, "Executing: "C:\windows\system32\msiexec.exe" /i "C:\Users\Crusisxx\AppData\Local\Temp\IXP593.TMP\iTunes64.msi" INSTALL_SUPPORT_PACKAGES=1" so I would navigate inside the folder in my temp called "IXP593.TMP, there you will find all the installation packages, copy all of those files and paste either on your desktop or a new folder ect, once done you can now click finish on the failed itunes installer, now whether or not where ever you decided to place your files you copied from that temp folder you will want to run Itunes64.msi or Itunes.msi ect, and run the installer, you should now have successfully of installed Itunes.

Nice one Crusisx. Best answer/solution I've found for this one. Cheers

WOW! Nice job. Finaly worked.

Thanks

Awesome!

Thanks Crusisx!

Can you reword this in simpler terms please? Like step by step. I have no tech experience, but am somewhat computer literate.

My computer was without antivirus software for about a week and I believe I encountered a virus in that time. Well I just re-installed McAfee and have a handful of updates to install. iTunes was one of them and when I went to update iTunes it did not properly install and I get the same error message. I can not find the location on my computer anywhere. PLEASE HELP!!!!!!!!!!!!!

For general advice see Troubleshooting issues with iTunes for Windows updates.

The steps in the second box are a guide to removing everything related to iTunes and then rebuilding it which is often a good starting point unless the symptoms indicate a more specific approach. Review the other boxes and the list of support documents further down the page in case one of them applies.

Your library should be unaffected by these steps but there is backup and recovery advice elsewhere in the user tip.

Along these lines, key not valid for use in specified state was a great help.

In my case I removed the RSA folder, and ran the 3 install programs from C:\Users\<username>\AppData\Local\Apple\Apple Software Update and all went well.

I tried many things including uninstalling and deleting temp files. What worked for me was to save the iTunes setup download, then right click on the exe and extract to a new folder. Run each of the *.msi in the order they appear leaving iTunes64.msi near the last to be installed. I hope my hours of frustration have helped someone else to resolve this debacle quickly.

Made a video on this, hope it helps

Thanks, Crusisx. This approach worked, both for iTunes and for the same issue with installing QuickTime.

I did have to install Apple Application Support from AppleApplicationSupport64.msi in the same directory, for iTunes to work.

What I figured out was that my Windows wasn't able to operate the new ITunes software and therefore I had to download the older version of it which worked! And make sure if your downloading the ITunes, if its for a 32 bit or 64 bit!
