How do I solve windows error 2? I'm using windows 7

Question

I am unable to access I tunes. The message "Windows error 2" appears and the message "Apple application was not found". It tells me to uninstall and then install I tunes, but the system won't allow that. I am using windows 7

For general advice see Troubleshooting issues with iTunes for Windows updates.
The section Install missing components has advice on breaking down the iTunes installer into the individual .msi files which might prove useful if Apple Application Support won't install normally.
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 the page in case one of them applies.
The further information area has direct links to the current and recent builds in case you have problems downloading, need to revert to an older version or want to try the iTunes for Windows (64-bit - for older video cards) release as a workaround for performance issues or compatibility with third party software.
Your library should be unaffected by these steps but there is backup and recovery advice elsewhere in the user tip.
