Establish centralised application delivery so that IT staff do not have to perform installations in person at workstations.

Perform company-wide application upgrades...overnight!

Problem...

Applications arrive on a CD, with a setup program that takes you through an extensive series of prompts and choices in order to install it. This is a fine system for home users with one computer, but for a company of any size it's a nightmare. You have a lot of computers, users, and applications, not to mention upgrades, and a choice of unpalatable options for bringing them together:

• Allow users to install their own software as they see fit. Every installation ends up being done differently, and you have no control over whether license agreements are being adhered to. Users have to spend time installing apps instead of doing their jobs. An installation that goes wrong can render a system inoperable.
   
• Have IT staff perform all application installations. This gives you a chance at standard installations, but if you have more than one person doing installations, chances are they'll each do it their own way. In a company with more than, say, 100 PCs, you need at least one full-time staff member doing nothing but performing installations and upgrades. Small, far away offices are difficult to handle. User installation needs at night or on weekends are problematic.

Furthermore, none of these methods work very well when you need to roll out an application to everyone, quickly. Let's say you're upgrading your word processor. Wouldn't it be nice to have everyone get the upgrade at the same time, without anyone having to go around to every system?

What is needed is a way to:

• Allow users to install applications whenever they need them, without requiring IT assistance or presence.
   
• Still allow IT to determine how applications are configured.
   
• Ensure that every application is installed the same way every time, automatically, without requiring decisions or input from the user.
   
• Allow IT to push important installations to all users, or a chosen set of users, automatically and simultaneously.
   
• Automatically ensure that installations conform with license agreements.

...Solution!

Fortunately, there is a way to do all of this. At H&A, any user in any office can simply choose from an extensive menu of preconfigured applications. Any application they select is installed without them having to run setup or make any choices at all. We can limit the number of allowable installations, thus enabling us to remain license compliant. And, we can make an installation happen automatically on all computers in the company at about the same time.

How have we done this? We use WinInstall, a centralised application configuration and distribution package that I can't say enough good things about. Here's how it works.

• When I install an application, I identify the changes it made. Changes generally include shortcuts created, registry changes, files copied, INIs modified, whatever.
   
• I tell WinInstall what those changes were. WinInstall creates a script, basically, for the application.
   
• A user running WinInstall is presented with a list of available applications. Selecting one and clicking Install is all the user has to do; WinInstall applies all necessary changes and configurations to the workstation. Voila, the user can now run the application.

It doesn't get much easier than that!

Anyone in any office can install an application that we have preconfigured, without having to involve us. This is very handy when someone in San Diego suddenly needs an obscure engineering application at 11 PM on a Saturday. We have upwards of 300 applications available via WinInstall. Most importantly, by using WinInstall, an application is installed the same exact way every time it is installed, thus ensuring consistency.

The AutoInstaller component allows us to deliver upgrades and fixes automatically. Nobody has to walk around to every computer to apply a patch.

Each application can be limited to a certain number of installations. License management handles itself. If all copies are already installed, someone must remove one before anyone else can install it.

We can limit application installation by just about any criterion: group membership, CPU type, version of Windows, available disk space, the existence (or absence) of a particular file or shortcut or registry entry, the presence of a file older or newer than (or matching) a particular date...

It would be impossible to quantify all the time WinInstall has saved the H&A IT department, and the staff, in the (almost 10!) years since we implemented it. Users can install apps at their own discretion, as they need them, without requiring any interaction with IT. And, as we standardised the setup of all the other offices, we simply copied our existing WinInstall set to provide them instantly with the same extensive suite of applications. (With some paring down to comply with licenses they owned, of course.)
