I read a nice article in Florian web site about Customizing msi installation through GPOs. In this article, Florian talked about how to add custom properties using ORCA(a windows SDK tool) to msi files and deploying it with GPOs. This procedure is really helpful to change some of the properties of msi files, EULA agreement status, installation directory, installation of sub components, and some of the msi checks. I thought it is helpful to my blog reads and posting it here.
