Description
Enter a multi-line description of the feature. This appears if the end user selects a
feature on the Select Features dialog box during installation. This text must fit in the
Feature Description area of the Select Features dialog box.
Level
If you are using the Installation Types page to determine which features to install for
a Typical or Complete installation, you can skip this field. If not, specify whether this
feature is installed for a Typical or Complete installation. The end user chooses
Typical, Complete, or Custom on the Installation Type dialog box (also called Select
Installation Type). During a Custom installation, the end user can turn features on
or off individually.
Each installation has an installation level, stored in the property INSTALLLEVEL.
Each feature has its own installation level value, which is set by this field. If a
feature's level is less than or equal to the installation's INSTALLLEVEL property, then
the feature is installed. By default, INSTALLLEVEL is set to 3 for a Typical
installation, and to 1000 for a Complete installation.
Normal
Set the feature's level value to 3, which means that it gets installed by default
for either Typical or Complete.
Never install this feature
Set the feature's level value to 0, which means that it won't appear during
installation, and won't be installed.
Always install this feature
Set the feature's level value to 1, which means that it gets installed by default
for either Typical or Complete.
Custom
Set the feature's installation level value yourself. Example: if you want a feature
to be installed for a Complete installation, but not for a Typical installation, set a
custom level value that's greater than 3 and less than or equal to 1000. The
Custom Value field becomes available.
Custom Value
If Custom is selected in Level above, enter the level value for the feature in this
field. For details, read the description of Level, above.
