To say iTunes is a pretty handy program is an understatement. It's pretty much the world's most used media player, and it doesn’t seem to mess up on a grand scale, but when there are blips and problems with iTunes, they seem to be insidiously annoying. Case in point: iTunes Error -42110.
You start iTunes. You wait for it to load. And it pops up an error message.
Even if you x-out of the error, it just keeps coming back every time you start iTunes. At the heart of the problem is a permissions error. Either through a conflict glitch or through a wonky update, iTunes disassociated all of the user account permissions it needs to confidently link purchases to accounts. It’s annoying, yes, but it’s also the sort of problem that’s relatively easy to tackle.
Try Running iTunes as an Administrator
This is the first thing you should do to make sure that your authorization is being recognized on the top level. To do this, search for iTunes in the Windows search box. The search box is located in the start menu of Windows Vista and 7. In Windows 8, you just start typing iTunes in the Metro screen and Windows will automatically begin searching.
When the iTunes icon appears, right-click it. You will have an option to “Run as Administrator.”
Try (Re-)Authorizing Your iTunes Account
The next step is to try and stop error -42210 by simply authorizing iTunes as an administrator.
A lot of this is just starting from the top and working your way down. Log into the administrator account on your computer. Once you’re logged in, check to be sure that you have the latest version of iTunes downloaded. (There’s no sense in doing this with an old version.) You can check for the latest version here.
Then run iTunes as an administrator like you did before. Once iTunes is open, x-out of the error and go to the menu button at the top left corner of your screen.
- Select iTunes Store.
- Select Authorize This Computer.
- Enter your iTunes username and password to authorize the computer.
- Once your information has been saved, quit iTunes.
Re-open iTunes to see if the message appears.
Try Authorizing All Users
You can have multiple usernames and accounts in the iTunes store. It may be that your permission error stems from the fact that you have multiple accounts and you bought a particular item while signed into a different account than you’re trying to use now.
Which account were you logged into when you downloaded that new song you heard? If it wasn’t your account, the other person will need to authorize the computer by going to the top left menu, selecting iTunes Store and then Authorize This Computer to have access to all of the material that you’ve downloaded in their account.
If you’re curious about which account owns a particular item, you can always check. Select a particular item in your iTunes library and then select File. Click on Get Info and you’ll be able to see the account name in the Summary tab in the box that appears.
Try Turning Off User Account Controls
The User Account Controls (UAC) system was a recurrent pain for Windows Vista users. It was the safety double-check that kept asking you if you wanted to let a program run. Later versions are better, but even so, toggling the user account controls on and off may be the authorization change needed to trip your iTunes account past the errors you’ve been experiencing. To do this you can go to
- Got to Start.
- Control Panel.
- In the Control Panel, select User Accounts.
- Next, click on Change User Account Control Settings if you’re in Windows 7. In Vista, you can select the option to "Turn User Account Controls On/Off."
- To disable the UAC, move the slider in the notifications all the way to the bottom of the information bar. In Vista, you’ll uncheck the box labeled “Use User Account Controls (UAC) to help protect your computer.”
- Click OK to save your changes and to auto-restart your computer.
Once the computer has restarted, you can choose whether or not to re-enable the UAC and at what level. Ideally it won't matter as far as iTunes goes because it's the resetting and restarting that will have hopefully reset permissions. Open iTunes and see if the message re-appears. If it does, go ahead and authorize all of your user accounts again in the iTunes store, then close iTunes, then restart it.
If none of the above authorizations are doing the trick, there is a way to muscle iTunes into resetting permissions.
Try Deleting the SC Folder
If nothing else has worked and you’re still stuck with an annoying iTunes error, your next step will be to remove a folder called “SC Info”. Deleting this folder will force iTunes to, well, remake it and in the process, reestablish links to digital rights permissions that are causing the unknown error.
To do this, close out iTunes and go to Start menu to select Computer.
For this to work, you need to make sure you can view hidden files and folders on your PC. In the Computer menu bar, select Organize and then Folder and Search Options.
In the menu box that appears, click on the View tab. On the tab, you’ll see an Advanced settings area. Look under Hidden files and folders to be sure that “Show hidden files and folders” is selected. Click OK.
For more information on Hidden Folders and how to manage them, check out our article on dealing with hidden content on your computer.
Once that's done, go back to Computer and then click on your C:\ drive. From there, select ProgramData then Apple Computer and finally iTunes.
Right click on the SC Info folder that you’ll find inside your iTunes folder and opt to delete. If you aren't comfortable deleting it, you can alternatively give it a new name. Just rename it and put some character, like an "x" at the head of the name.
Once the folder is deleted, restart iTunes. In its launch sequence, iTunes will search for the SC Info folder and - not finding it - will regenerate it. This should force iTunes to reset all permissions and hopefully the error is now gone. For good measure, you may want to (yet again) authorize your computer to play your purchases. Be sure to authorize the computer for all accounts you have that you use on the computer.
