I am having an issue when trying to either update or install/repair Infragistics Ultimate 17.2

On anything I try I run into the following messages:

Version Utility: An error occured during download, please check internet connection and retry again.

Visual Studio Extension: An error occured during download, please check internet connection and retry again.

Visual Studio Template Gallery: An error occured during download, please check internet connection and retry again.

Any help would be appreciated.
