Runtime error R6025 Pure virtual function call....the program shuts down as soon as its opened

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.

If you've already tried a complete uninstall and reinstall try opening iTunes in safe mode (hold down CTRL+SHIFT) as you start iTunes, then going to Edit > Preferences > Store and turing off Show iTunes in the Cloud purchases. You may find iTunes will now start normally.

Thanks - this fixed my "iTunes has stopped working" error right after startup. The error came out of nowhere, I've been successfully using iTunes for years. For those who might be interested, I'm using a Win 8 PC.
