Can't install iTunes. "Error writing to file..."

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. When reinstalling right click on the downloaded setup file and use run as administrator.

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, or want to revert to an older version if the current one won't work properly for you at the moment.

Your library and device backups should be unaffected by these steps but there are links to backup and recovery advice should it be needed.

That one's consistent with disk/file damage. The first thing I'd try with that is running a disk check (chkdsk) over your C drive.

XP instructions in the following document: How to perform disk error checking in Windows XP

Vista instructions in the following document: Check your hard disk for errors

Windows 7 instructions in the following document: How to use CHKDSK (Check Disk)

Select both Automatically fix file system errors and Scan for and attempt recovery of bad sectors, or use chkdsk /r (depending on which way you decide to go about doing this). You'll almost certainly have to schedule the chkdsk to run on startup. The scan should take quite a while ... if it quits after a few minutes or seconds, something's interfering with the scan.

Does the chkdsk find/repair any damage? If so, can you get an install to go through properly afterwards?

🙂 You're welcome! Glad you got things working again.

I've tried fixing c: file errors, but my PC says there are none. I'm still having the issue where I cant write to that file. Please help me.
