All you need to do is call
Execute-MSI -Action Install -Path ‘$dirFiles\yourdirectory1\yourmsi1’
Execute-MSI -Action Install -Path ‘$dirFiles\yourdirectory2\yourmsi2’ -Transform ‘$dirFiles\yourdirectory2\yourmst2’
$dirFiles is the variable for the Files directory in the toolkit.
So on and so forth for each msi and mst and it should run fine.
If you look in the AppDeployToolkitMain.ps1 as the global variables are declared in there.
Update – I have just replaced the 3.6.4 extensions script with the one I customised for 3.2.0 and it is all working again. I don’t see anything in particular that would affect the extensions script, but maybe I am missing something.
I had a couple of functions that worked in the older version of the toolkit – 3.2.0, and they used to show in the help file. I have copied these into the new version, 3.6.4, extensions script and I no longer see them in the help file. Has something changed? I have followed the above, but they don’t seem to appear.
