can anyone help it wont let me install itunes.

Do you get an error message when you try to install iTunes? If so, what does it say? (Precise text, please.)

These ones are typically caused by underlying problems on the PC that also often cause Windows Updates to fail to install. If we can fix the Windows Update trouble, we can usually get the iTunes trouble cleaned up en passant.

Go into your Windows update and try to check for new updates. If updates install, stock up on the ones you're behind on, restarting the PC if requested to do so. After the restart, try installing iTunes again. Does it go through this time for you?

If windows updates fail to install, go into your Update History and doubleclick the failures. What alphanumeric codes appear for you? (For example, 8007000B.)

Okay. Let's try the following MicroSoft fixit:

Does that get your Windows Updates installing again? If so, stock up, restart the PC and try another iTunes install.

🙂 You're welcome. Glad you got things sorted out.
