SynopsisWhen importing an MSI into AdminStudio, in the Import status dialog you see a "Unable to create transform file" message and no Software Tag transform is created.
DiscussionThe cause of this issue is because of custom columns in the feature table. The software tag transform that we create adds a new record to the feature table.
