Error code: 0x800F081F
This error code can occur when an alternative
installation source is specified and one of the following conditions is true:
·
The location that is
specified by the path does not contain the files that are required to install
the feature.
·
The user who tries to
install the feature does not have at least READ access to the location and to
the files.
·
The set of
installation files is corrupted, incomplete, or invalid for the version of
Windows that you are running.
To resolve this problem, make sure that the
full path of the source is correct (x:\sources\sxs) and that you have at least
Read access to the location. To do this, try to access the source directly from
the affected computer. Verify that the installation source contains a valid and
complete set of files. If the problem persists, try to use a different
installation source.

installation source is not specified or is invalid and if the Specify
settings for optional component installation and component repair Group
Policy setting is configured to "Never attempt to download payload from
