Itunes 9.2 Errors Solution (Rollback)

Question

Hi Everybody,
As we all know the 9.2 is severely flawed and is making syncing impossible without crashes, this worked for me and hopefully it will for you too, please follow the instructions carefully. This will bring you back to 9.1.1 which works fine.
1. Save a copy of your library file as a backup, just in case (it's in the My Music/itunes folder, and it’s called "iTunes Library.itl"). I also printed out 1 page of my music library sorted by Date Added so I’d have a list of the most recent songs I had added (I had bought some stuff after upgrading to 9.2, and I knew they’d need to be manually imported after I rolled back to my earlier library.
2. Remove everything installed by Apple in "Add/Remove Programs" in Control Panel (it might be called "Programs and Features" in Vista). I removed itunes first, then Quick Time, then Apple Mobile Support, Bonjour, and anything else that came from Apple. Apparently this is important when you roll back to an earlier version of itunes, or so the posts I read told me.
3. Restart your computer.
4. When you're started up again, download itunes 9.1.1. I just went to File Hippo, searched for "iTunes". It only showed itunes 9.2 results, but all the older versions are located in with the most current version. Go to "itunes 9.2 (32 bit)" if you have a 32 bit OS (like my Vista) and go to "iTunes 9.2( 64 bit)" if you have 64 bit OS (Windows 7?). After you select the one you want, you'll go to a page that has all the older versions listed on the right - pick itunes 9.1.1, download it and install it. There are other ways to get old iTunes versions – this was just the one that worked for me.
5. When it's installed and ready to go, it may give you an error message about the library being created by a later version of iTunes --- I just cancelled it out, because you are replacing the library anyway. Also, my IT guy said to make sure the “Keep iTunes Organized” checkbox in Preferences/Advanced” is unchecked when you replace libraries, which I did, although I’m not entirely sure why. All I know is it worked.
6. Replace your newly created empty library file with the library file itunes created in version 9.1 before it upgraded to 9.2. To do that, go to your itunes folder (usually in the My Music folder) and delete the "iTunes Library.itl" file that the new install of 9.1 just created. I didn't mess with any of the others (iTunes Music Luibrary.xml; Extras, Genius, etc., and I was fine). Then find the "Previous iTunes Libraries" folder. Every time itunes upgrades, it saves a version of the pre-upgrade library file in that folder, with a date. Locate the "ITunes Library 2010-06-25.itl" file (the date will be whatever date you installed your 9.2 update). Change the name of that file to "iTunes Library.itl" and copy it into the root itunes folder where all the iTunes library/Extras/Genuis files reside (i.e. where you just deleted the new library the install created).
7. Fire up iTunes, and your old library and music and playlists should show up just like it did before 9.2 was installed, all purty like. You may have to clean up a few things or add back any songs you bought during 9.2, but for the most part you should be back in business.
Hope this helps.

Answer 1

From Chile. Today i've fixed the problem of this issue. The solution was.
1° Uninstall Itunes, Apple Device Helper and all Apple product from Control Panel > Software Management.
2° Rename the folders (or save in another folder) located in Documents & Settings > User > Aplication Data > Apple. User is your personal user and "all users".
Download Itunes.
Reinstall the software.
And it works.
Also, before and i dont know if this was part of the solution, i've searched sqlite3.dll and the one located in folder apple device manager don't delete. Copy and paste in the another location (in my case ma-config)
Hope this can resolve this problem.
