When trying to install Intel Parallel Studio XE 2018 update 1, selecting Update only installs the available required components and does not install the remaining required components.
To resolve this, close the installer and do one of the following:
In Intel Software Manager, select Download Only to download the full web image. Once the download is complete, select Install.
Go to the Intel Registration Center and download the online or offline installer of the required product update, and then install it.
