No, if they bought it, then its theirs. You may wish to contract iTS for options in case it was part of the Mac Acceptance.

I just installed the latest version of iTunes, but when I went to open iTunes I got a message saying registry settings used to for importing and burning CDs and DVDs are missing and I should reinstall iTunes. Really?

I just installed the latest version of iTunes, but when I went to open iTunes I got a message saying registry settings used to for importing and burning CDs and DVDs are missing and I should reinstall iTunes. Really?

I'd start with the following document, with one modification. At step 12 after typing GEARAspiWDM press the Enter/Return key once prior to clicking OK. (Pressing Return adds a carriage return in the field and is important.)
iTunes for Windows: "Registry settings" warning when opening iTunes

My iTunes says this copy is corrupted or not installed correctly and I should reinstall iTunes. Will this wipe out my library

When I hit my iTunes icon I get an error message that says "this copy is corrupted or not installed correctly. Please reinstall iTunes".
So, my question is, if I reinstall iTunes will my music library be wiped out?

Let's try a repair install of iTunes first.
Restart the PC. If you're using Vista or 7, now head into your Uninstall a program control panel, select "iTunes" and then click "Repair". If you're using XP, head into your Add or Remove Programs control panel, select "iTunes", click "Change" and then click "Repair".
Can you launch your iTunes now?

I have pages, numbers and keynote on my macbook pro, but when i try to use the apps on my new iMac it will not let me save

I purchased Pages, Numbers and Keynote for my MacBook Pro and iPad last year. I just purchased a new iMac for my wife and it came with iWorks. When I try to save a document on the iMac it tells me I must buy an iWorks serial number, but the App Store shows the applications as installed and will not process the request. How do I correct?

Did you pay for iWorks to come preinstalled on the iMac? Because it sounds like what you have is a trial version, which is why it is stating that you need to buy a serial number.
I suggest that you delete the entire trial iWorks suite. Once they are safely in the Trash where the Mac App Store can't see them, you can sign into your account on the MAS and download the MAS versions that you own a license to use.

I tried to change my persona and firefox keeps defaulting to my old one before I updated my browser.Is there anyway to change this without uninstalling the whole browser? Because I'd like to keep all my bookmarks and such. Thanks

I uninstalled all other personas besides the default and the one I want and it still goes back to the old persona unless I keep firefox on default. \The desired persona is a sports one and it keeps defaulting to a surfing one.

Hi. The two user tips both describe a sequence of steps that should get your library from the point where it threatens to wipe data from your device to where it is syncing normally, while recovering as much information as possible. It may still be necessary to wipe and reload the device but this should only take place once all the data that can be recovered has been recovered.
Doing step 1 of 8 and then complaining things aren't the way you want them to be yet strikes me as premature...
Since you appear to have all your media content, and we are discussing an iPod classic, not an iOS device, the main worries are already taken care of. What's left is ratings, playcounts, playlist membership and checked status. Since your device holds only part of your library at best you could only recover the missing data for the content that is on the device using third party tools.
Recreating the previous checked/unchecked status of every track in your library from where you are now may not be that easy. Syncing with selected playlists has many advantages, one of which would have been that you would have a named playlist that could have been retrieved by 3rd party software if you had used this method.
You haven't explained what caused your problem in the first place, but if you have a Previous iTunes Libraries folder holding old copies of your iTunes database (generated with each iTunes update) then it would be possible to restore the most recent of these and then update the library with any changes in your media folder.
BTW Apple doesn't offer free support for this kind of issue with iTunes.

updated itunes and now get the following message.
this copy of itunes is corrupted or not installed correctly. please reinstall
what has caused this?
in my downloads folder i have itunes64Setup.exe do I just run this ?
or will this overwrite my existing data and I'll have to set up my library from scratch.
as its an ipod classic with 120 Gb of data i'd rather not have to set it up all again

I have many thousands of songs in my itunes library. Unfortunately, most are now pointing toward .jpgs instead of the m4a files in my itunes library. Is there anyway to fix this without reimporting all the files into itunes from scratch??

OMG...I'm glad to know I'm not the only one. Since my computer is a goner, I don't have any other way to access all that music.

HT1349 My computer popped up with an update from iTunes several days ago. I downloaded the update and when I went to open iTunes, it won't open. I've tried to download again from the website, but it still gives me this error message. Missing MSVCR80.dll

My computer popped up with an update from iTunes several days ago. I downloaded the update. When I went to open iTunes on my computer, it gives me the following error messages...
Missing MSVCR80.dll file.
Error 7 (Windows error 126)
I tried to download iTunes again from the website and repair the problem, to no avail. I've tried several times, but cannot get it to open. I have a Windows 7 machine. My iPhone 5 and iPad work fine and have not asked me to update. I've never had a problem with iTunes before. I hate to delete it entirely from my computer and start over. I'm afraid I'll lose all the music I have downloaded there. What do I do?

Just reinstall iTunes. I done the same thing without losing my iTunes library.
BUT if you did lose your music follow through these:
