How do I use Orca and mst to deploy your products

" We want to roll out your products using the MSI and an accompanying MST.

We have dutifully got Orca and opened up the MSI and then got very lost trying to find which fields I should edit to input the licenses key and user details, can anyone point me in the right direction?"
 

You will need to add additional rows to the Property table in the .msi file, then save the changes in the transformation file (.mst). In order to pass your license information, make sure to add a row with a name " KEY " and value your serial key. If you only want to install some of the components, make sure to include an ADDLOCAL row with a value then a coma-separated list of components you want installed:

 The full list of components you can include in ADDLOCAL, as well as a full list of other parameters that you can add to the property table, can be seen when you launch the .msi file in a GUI and click the help button. Additionally you can find the same list attached to this forum topic.
