While this property can only be used during an initial install, the ThumbnailPreviewHandler property can be run anytime post install. Installs and uninstalls the Windows Explorer thumbnail preview handler. For example, when invoking an MSI ( msi=AcroPro.msi), you can only use space-separated Adobe properties (flag/value pairs connected by an = sign) and MSI switches for example, you can use /qb!+ but not /sAll in this section. The CmdLine should only contain values supported by the item the EXE invokes. There may be multiple sections depending what the EXE should invoke (other MSI’s or EXE’s). Do not place Adobe properties or MSI switches here for example, you can use /sAll but not /qb!+ in this section. : Setup.exe first executes the Adobe flags for CmdLine. Before deployment, open Setup.ini, verify it contains all the properties you need, and edit it as neccessary. The Setup.exe file uses Setup.ini as it’s configuration file. As you customize the installer with the Wizard, the Setup.ini file automatically updates. The bootstrapper Setup.exe file uses setup.ini as its configuration file.
You can use your customized MST for bootstrapper deployments.
