Fix “iTunes Does Not Start Up” by Creating a New iTunes Name
First of all, you need to see if the problem is your music library, quit iTunes if it is running, then go to your Music folder located inside your home folder. Rename the “iTunes” folder something like “iTunes Backup”.
After that, relaunch iTunes. If it launches successfully it will create a new iTunes folder. If this works, then something is messed up with your music folder. If this still doesn’t work, delete any new folders iTunes creates and restore “iTunes Backup” to its original name.
Fix “iTunes Won’t Launch” by Add A New iTunes Library File
Step 1: Confirm that your Apple device is connected securely to your computer. If you are not trying to access iTunes via an Apple device, or if your device is connected correctly, continue to step 2.
Step 2: Configure your firewall to allow iTunes to connect to the Internet. Many firewalls block software programs’ ability to get online as a security precaution. This is because some spyware and malware is designed to transmit personal data from your computer. Making iTunes a trusted program within your firewall software is necessary for it to function properly.
Step 3: Create a new iTunes library file. An unstable or corrupted library file can cause iTunes to suddenly quit or not open at all. Recreating a library file is a lengthy process that depends heavily on the operating system you are using. See the iTunes Support page under Resources for detailed instructions.
Step 4: Reinstall iTunes on your computer. If no other troubleshooting steps are successful, then you can try the method 3.
