Info:

MSI packages for Hach WIMS that are NOT Patch MSI's (see Q12287) are files that look like "wims_ZZZZ.msi" and fall into two categories:

1. Packages that are installed by the Platform Installer Bootstrapper
   
2. Direct Server-Side Interface MSI packages that can be installed stand-alone provided your system meets the prerequisites (TODO: link to prerequisites article)

Right clicking and MSI package, choosing Properties and then clicking on the Summary tab will tell you in which category it falls:
