Hi,
Thank you for posting the query in Microsoft community!
From the problem description I understand that, you cannot install Utilities and SDK for Subsystem for UNIX-based Applications.
I would suggest you to perform a standard installation, here are the steps:
a. Download the Utilities and SDK for Subsystem for UNIX-based Applications from the Microsoft Web site (http://go.microsoft.com/fwlink/?LinkId=139521).
b. In the Utilities and SDK for Subsystem for UNIX-based Applications Wizard, click next.
c. In the User name box, type your name. If the name of your organization does not show in the Organization field, enter the name of your organization.
d. Read the Microsoft Software License Terms carefully. If you accept the terms of the agreement, click accept the terms in the License Agreement, and then click next to continue installation. If you click I do not accept the License Agreement (Exit Setup), the installation procedure terminates.
e. To install default Utilities and SDK for Subsystem for UNIX-based Applications components in the default directory, click Standard Installation, and then click next.
