I cannot seem to get MST files to be seen when I import a software release.
Steps taken:
Manage -> Software
Navigate to Releases
click "Import"
Change source to "Access package from an existing UNC"
Enter the location of the package
click "Display location"
Click "Next"
leave "Update an existing software resource" checked
click OK
go to Add Command, make sure command type is "Install" and click "Edit" and... the "Add" button under "Add transforms to be applied to the MSI at run time" is greyed out.
