Missing Unity Installation Components: WebPlayer , StandardAssets , VisualStudio

Greetings, Upon installing Unity I was given the following prompts from the Unity 5.2.1f1 Download Assistant;

"Ini file doesn't contain cmd for component WebPlayer. Don't know how to install this"

"Ini file doesn't contain cmd for component StandardAssets. Don't know how to install this"

"Ini file doesn't contain cmd for component VisualStudio. Don't know how to install this"

This is for the 64-bit version for windows. Will these errors impact my use of Unity? If so, how do I remedy the problem? Thanks
