Original Title: Error code 2503/2502.
I had to restore my computer to factory settings, and after I did this I now get error code 2503 and/or 2502 when trying to install iTunes or update Java.
I have tried to install by right-clicking the .exe and selecting "Run as administrator."
I have seen other suggestions that say to check Windows Installer, but I have searched for this on the computer and cannot find anything called Windows Installer.
My computer is currently up-to-date with all updates. I am running Windows 7 64-bit Home Premium.
