Q: iTunes error 7 (windows error 5)

Same here!  I cannot even downgrade to another version of iTunes…Same error pops up.

Like many others I have been reading about online I am having the same error.  I tried the fix listed above and simply wasted 30 minutes of my time. I scheduled a time for Apple to call and help me through this and their solution was for me to call Microsoft for some reason?!!  iTunes made me upgrade then stopped working - I really don't see how this is a Microsoft problem??

Like Darren if a solution is not found quickly I will also have to sell my phone as the only way to get videos and music on my phone is through the software that you made me upgrade, broke and won't help me fix.

Hi!

I tried to fix with this steps but doesn't work. My problem started when iTunes made me upgrade. Have any other solution?

It may be that you need to repair the Windows Installer Service before reinstalling iTunes.

See http://blogs.msdn.com/b/astebner/archive/2006/07/20/673408.aspx

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 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.

turingtest2 thanks for the response but I continuing with the same problem.

The steps that I followed (several times) are:

1. Uninstall (in this orden)

• iTunes
• Apple Software Update
• Apple Mobile Device Support
• Bonjour
• Apple Application Support

2. Restart the computer

3. Try to delete (but not exist)

• C:\Program Files (x86)\Bonjour
• C:\Program Files (x86)\Common Files\Apple
• C:\Program Files (x86)\iPod
• C:\Program Files (x86)\iTunes

4. Run this command in the windows console (cmd)

• Run %windir%\system32\msiexec.exe /unregister
• Run %windir%\syswow64\msiexec.exe /unregister
• Run %windir%\system32\msiexec.exe /regserver
• Run %windir%\syswow64\msiexec.exe /regserver

5. Restart the computer

6. Install iTunes

Any other solution?

At step 6 try the section Install missing components and install the parts of iTunes one at a time.

Thanks for the new advice turingtest2. I have tried to doing all again and at installing the individual .msi components in alphabetical order, but with the same error

Did any of the components throw an error when the were installing?

tt2

No, any problem. Only when I try to open iTunes after the installation.

Hmm, locate the iTunes entry in your start menu, right-click on it and click Properties. On the Compatibility tab check the Run this program as an administrator box. Does iTunes open normally now? If so you should be able to remove that check box and have it continue to run normally.

No, iTunes continuing with the same error after check the Run this program as an administrator box. As well I tried to re-installer iTunes.
