Unable to install itunes

I did have itunes but couldnt update it, so i uninstalled it altogether and tried reinstalling it but continue to receive this message :

An error occurred during the installation of assembly

'Microsoft. VC80.CRT,type="win32",version="8.0.50727.61

95",publicKeyToken="1fc8b3b9a1e18e3b",processorAr

chitecture="x86"'. Please refer to Help and Support for

more information.

I have tried multiple times to redownload itunes and continue to receive this message before itunes is able to fully download. What would be the next step to take?
