This is an Installsheild setup wrapped around an msi. Vendor setup performs download and install of Microsoft .Net 1.1 SP1, reboots and then install from extracted msi.
The vendor msi has many custom actions that require the MS .Net to be available along with Postscript printer drivers and office/IE versions. So make sure you have these before hand otherwise the vendor install errors out.
Steps to package.
1. Launch vendor exe. This will first extract the vendor msi in the temp folder location and start the download of the MS .Net 1.1 SP1. Copy the msi and .net file and cancel out of the install.
2. Preinstall MS .Net 1.1 SP1, Any recent HP/Printer PS driver, Office.
3. Transform the vendor msi and permission out the install folder and HKLM registry entry.
