Apple Application Support Windows 10 x64 Fresh Install Fails

This error makes iTunes completely inoperable on Windows 10. It's ridiculous that this error has been occurring for months across different platforms and hasn't been fixed. Surely I'm not alone in this.

It has occurred on both my main desktop and laptop with fresh Windows 10 installs. It's no longer in technical preview. It's time this was resolved.

(This error occurs during the iTunes setup. Yes I have removed and reinstalled; now trying to install application support separately. For the rest there have been no errors.)

"An error occurred during the installation of assembly 'Microsoft.VC80.CRT,type="win32",version"8.0.5072 7.6195", etc.
