i need a version of itunes for windows 8.1 I deleted 12.7.1.14 and don't seem to be able to install anything now

https://support.apple.com/downloads/itunes

Follow the path to Windows and then to old versions. There isn't a direct link I can provide.

Feel free to use these in future:

• iTunes 12.10.10.2 for Windows (32-bit) - iTunesSetup.exe (2020-10-19) - Final build for Windows 7 & 8
• iTunes 12.10.10.2 for Windows (64-bit) - iTunes64Setup.exe (2020-10-19) - Final build for Windows 7 & 8
