Q: error message iTunes64 Setup.exe is not a valid Win32 application.

I've tried a few times to update my laptop with latest version of iTunes, even have uninstalled older version, and I just keep getting this message. What am I doing wrong? How do I fix it? I have Windows 7, 64-bit system.

I wouldn't have even tried to update, but when I plugged in my new iphone 4S to download my itunes librarby to it, i was prompted to get the most recent version. Now I don't have anything. HELP!

In the course of your troubleshooting to date have you worked through the following document?

Yes, I've done that a couple times now and still get the same message.

Perhaps try downloading and saving a copy of the installer to a different (64-bit) PC. Copy the iTunes64Setup.exe installer to an external hard-drive, or a large-enough thumb drive or burn it to a CD-R. Carry the installer back to your PC, copy the installer to your hard drive. (Don't run the install from the ExHD, thumb or CD-R.) Start the install by doubleclicking the iTunes64Setup.exe file.

Does that go through any better for you?
