The programs and files now installed will have a check mark in the box. Note there are 3 states of the selection box. Empty means the feature is not installed. Checked with a white background indicates the entire feature is installed. Checked with gray background means only part of it is installed.
Lets review how to look at the selections.
If you click a box, you change the selection. If you click on the words, nothing changes but you get a description of the feature. See Fig 1. If the selection box is gray and the statement says 5 of 7 components selected, click the Details button to see the sub selections. See Fig 2 .
