I created a transform for a vendor's .msi using Wise Package Studio. When importing the .mst into Software Manager, I receive the error "An invalid file handle was associated with <path to .mst>." This generally occurs when the vendor's .msi was created with a non-Wise product.
Steps to Reproduce:
The import begins, and then you receive the error "An invalid file handle was associated with <path to .mst>."
In the case where you select the option Apply transform to a blank Windows Installer database, the .mst cannot be applied to our blank template.
In the case where you specified an Application / Package that is already imported into Software Manager, the .mst cannot be applied to the .msi. This is caused by additional tables and properties that are added to the .msi during import.
If you were selecting Apply transform to a blank Windows Installer database option, you will need to import the .msi and select that package on the Select Target Package dialog. In either case, perform the following to import the .msi:
By selecting this option, the .mst can still be applied to the .msi after import as no additional tables or properties are added.
