Taking a mulligan on PC setups

System administrators dread new software rollouts. In mid-size to large
agencies and departments, it can take weeks to get a new software product
installed on all the workstations of the users who need it. And unforeseen
conflicts with existing software can easily send even a carefully planned
deployment to the brink of chaos. Enter PictureTaker.
The idea behind LANovation's PictureTaker is simple. True to its name,
it takes snapshots of your PC before and after installing a new software
product, and the differences tell you precisely what changes the new program
has made. There are other software products that watch a program during
installation to see what changes it makes to the system, but PictureTaker
does a more thorough job than other products I've tested.
I installed PictureTaker on a computer running Microsoft Corp.'s Windows
2000. The program immediately launched a wizard that led me through four
simple steps. First, the program took a few minutes to scan my PC to take
a baseline picture. Then it prompted me to install a program, and as a test
I installed the popular WinZip file compression program from WinZip Computing
Inc. Under the wizard's prompting, I saved the baseline picture to a file
and then created a single new file containing a package for installing the
WinZip program onto another computer.
I was delighted to find an editor that allowed me to view the package file
I had created. The editor surprised me by showing that WinZip has a much
more complex installation than I expected, with many changes to the Windows
registry and other system files. This editor can also compare pictures before
and after running a program to see what changes were made to the PC or to
detect where the program stores its settings.
The editor allows you to make changes to installation packages, such
as adding, modifying and deleting registry entries, adding and deleting
files and folders, modifying system files and so forth. I would like to
have been able to drag and drop objects between package files, but otherwise
the editor gave me every option I could think of. Sophisticated users can
create REG files, which are used to make registry modifications on client
PCs independent of any new program installations.
PictureTaker is basically program installation software, and it can
be used with software distribution products such as Microsoft's System Management
Server (SMS), Novell Inc.'s ZENworks and Computer Associates International
Inc.'s Unicenter TNG.
In my case, after installing the client program to my workstation, I
simply placed the update package onto a file server and modified the server
log-in script. As users in the appropriate group logged in, the new program
package automatically installed on their PCs. The operation was transparent,
and the users were not aware the install was being done until the new program's
icon appeared on their desktops.
PictureTaker did not forget mobile users. Another wizard guided me through
a few simple steps that placed the new install package as a download selection
on my Web site. If the client software is not already running on the user's
PC, do not despair. PictureTaker allows you to transform package files into
self- installing executable files.
One of my favorite parts of PictureTaker is the included Conflict Checker.
This program allows the administrator to compare two packages before they
are installed on the client computers to see if there are any conflicts
between them, such as different versions of DLL files or conflicting registry
PictureTaker is a mature, bug-free product in a competitive industry.
It would be nice to have additional network distribution features, such
as those in InstallShield Software Corp.'s NetInstall. But for overall flexibility
and ease of use with nearly all the options you can think of, PictureTaker
is an excellent choice.
