MYOB didn’t do so well at creating their .msi files in Premier 11, and so you have to tweak them a little before you’ll be able to deploy the application via Group Policy. Here’s how to do it…

1. Install a copy of Orca
2. Open Premier’s MSI file with Orca
3. Modify Directory => ISYourCompanyDir to “MYOB|MYOB”
4. Modify Directory => ISYourProductDir to “PREMIE~1|Premier 11″
5. Modify Directory => KEY_NAME_SC to “MYOB|MYOB Premier 11″
6. Save the MSI, close Orca, and then deploy it via GPO in the normal way.
