Thinapp

3 options to know of in Package.ini (for win7 installs, 1 user per desktop, etc):


MSIDefaultInstallAllUsers=0
MSIRequireElevatedPrivileges=0
// This makes the currently logged on user to simply and silently install the msi
// Wow! This is 2 years old?
MSIStreaming=1 - see kb.vmware.com/kb/1028385

// With this you can create an MSI that allows steaming and full install too.

Also http://blogs.vmware.com/thinapp/msi/ is a nice source for info.
Cheers!
