Hello and welcome to our forums,
To shorten the installation time you can build your setup pacakage as an
MSI with CAB outside. ALso, if you build an EXE setup type you can build it as an EXE with resources outside. This way the CAB extraction operation will be eliminated from the installation process.
You can also use the options under the "Minimize Installation Time" section from
"Install Parameters" page.
All the best,
Daniel
