Unable to update iTunes. Get 'iTunes has an invalid signature. It will not be installed.' When I reboot, get message 'Apple Sync Notifier.exe entry point not found'
Please help...need to get newest update so I can activate my new IPhone4. Thanks

That suggests that the installer is getting damaged during the download.
I'd first try downloading an installer from the Apple website using a different web browser:
http://www.apple.com/itunes/download/
If you use Firefox instead of IE for the download (or vice versa), do you get a working installer?

    With Windows Explorer, navigate to your C:\Program Files\Common Files\Apple\Apple Application Support folder.
    Copy the SQLite3.dll that you should find there, navigate to the nearby Mobile Device Support folder, and Paste it in there also.
    Restart the programme all should be well
    In case that your OS is (64 bit)
    1. Open windows explorer, go to location C:\Program Files (x86)\Common Files\Apple\Apple Application Support
    2. Copy file "SQLite3.dll"
    3. Now paste it in the folder  C:\Program Files (x86)\Common Files\Apple\Mobile Device Support
    4. Restart the programme, it should not display that message, it should be clear.

  • I'm trying to download itunes 10.5 (windowsxp w/servicepack3) and i get "Itunes has an invalid signature.It will not be installed". Suggestions?

    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.

  • Error "itunes has an invalid signature". Will not install. Why?

    Every time I try to update iTunes on my desktop computer I keep getting the same error message "iTunes has an invalid signature. Will not install. Why am I getting this message? and how can I fix it.
    ITunes came with the new HP I purchased in 12/2013. I have had a problem only with updates. I thought about uninstalling on my desktop but do not want to lose my songs. Was hoping to find a better solution than uninstalling and then re-installing.
    Any how would be appreciated.

    The error suggests some sort of corruption with the file you downloaded. Clear your browser's cache and download a fresh copy of the iTunes setup file.

    Thank you for using the Apple Support Communities

  • When I try to update to Itunes 11 I get an error message saying that Itunes has an invalid signature and wont be installed. I use Windows 7.

    Everytime I try to update to Itunes 11 I get an error message saying that Itunes has an invalid signature and can't be installed?  I have tried to install it two times and get the same message each time. Any solutions to my problem?? Those who have installed ITUNES 11 is it hard to work with? maybe im lucky it wont update?? I don't know.

    That suggests that the installer is getting damaged during the download.
