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 installer and use run as administrator. It may also help to temporarily disable any non-Microsoft anti-virus.
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, need to revert to an older version as a workaround for installation or performance issues, or compatibility with third party software.
Your library and device backups should be unaffected by these steps but there are links to backup and recovery advice should it be needed.

Try the advice in VC80 errors and/or Install missing components. See also the Microsoft tool mentioned in Note 1 to the second box which might be able to drive through the install. Obviously your iTunes 12 library isn't going to be compatible with iTunes 11 so you will need to rebuild that. The minimum build for devices running iOS 11 is iTunes 12.6.3.6.

I did do that but didn’t work
I even deleted the some files in my drive that has down loads
At what point in the process do you get stuck? Have you used the notes below the second box for example?
tt2
Yes of course
Which build are you trying to install now? Did you run the installer as the administrator?

Sorry I mean install not uninstall at the question on the top I tried running it as administrator it did not work I’m trying to install iTunes 11.0 then there was that error. error 7 Error 127
is there a easier way to do this
Clearly not or it would have installed correctly already. Since it hasn't you need to work through possible workarounds.
