Why do I face error 7 Windows error 193 when i try to reinstall my iTunes? I've tried few times uninstalling and reinstalling but it seems that it doesn't work.

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 the 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 are running 64-bit Windows and the above steps haven't helped try installing the version of iTunes that can be downloaded from this support document. iTunes 12.1 for Windows (64-bit — for older video cards)
