VBScript Software Installation

With as often as I deploy software, I created a standard VBScript template to use when needing to create an unattended application installation. One thing that I do not have in this script is and uninstall procedure, which I usually do when deploying software, as to uninstall the older version before installing the newer. I do not depend on the application installation to take care of the uninstall of older versions because I have run across too many apps in the past that did not properly uninstall before starting the new install.

So in this script, the parts you will need to modify are the global variable LogFolderName to be the name of the folder you wish for placing the log file at. The TempFolder constant may also need to be changed if you do not wish for the log file folder to be under c:\temp.

If this is a simple MSI installer, I have already completed most of the script for deploying the MSI. The only part that might need to be inserted is if there is a transform file.

You can download the script from here.
