First, you'll need to download the .msi (Special Installation Only) from Quest.com. If your Oracle client is 32-bit download the 32-bit version, else download the 64-bit.

Retrieve the license .xml file

1. Install manually the .msi
2. Launch the application and register the license key (Site message, License key)
3. Close the application, copy the file ProductLicenses.xml from this folder:

%LOCALAPPDATA%\{08439167-4CA5-48E9-A810-A3A7C0B80B06}

*Put the .xml file with your .msi file.

Create an .MST file

With the help of an .msi file editor as Orca, InstEd, etc. In this example we'll use Orca.

1. Right-click on the .msi file, choose Edit with Orca
2. In the top menu, choose Transform -> New Transform...
3. In the Directory Table, create a new Row for the Common AppData (C:\ProgramData);
   • Directory: CommonAppDataFolder
   • Directory_Parent: TARGETDIR
   • DefaultDir: .
4. Still in the Directory Table, create a new Row for licenses directory (C:\Programdata\{08439167-4CA5-48E9-A810-A3A7C0B80B06});
   • Directory: DirProductLicenses
   • Directory_Parent: CommonAppDataFolder
   • DefaultDir: {08439167-4CA5-48E9-A810-A3A7C0B80B06}
5. Move to the File Table, add a new Row for the ProductLicenses.xml;
   • File: ProductLicenses.xml
   • Component_: ProductLicenses.xml
   • FileName: ProductLicenses.xml
   • FileSize: 314 (from the file properties)
   • Attributes: 8192
   • Sequence: 595 (Increment the last existing sequence number)
6. In the Component Table add the following row;
   • Component: ProductLicenses.xml
   • ComponentId: {01A64F7E-2CCC-4E44-95B9-D9F2DB1D4F06} (Use one generated from a GUID generator like https://guidgenerator.com/, the GUID must be UPPERCASE)
   • Directory_: DirProductLicenses
   • Attributes: 0
   • KeyPath: ProductLicenses.xml
7. In the FeatureComponents Table, add the following row;
   • Feature: Toad_Full_Install
   • Component: ProductLicenses.xml
8. In the Media Table, add the following row;
   • DiskId: 3 (Increment the highest existing value in the Media Table)
   • LastSequence: 595 (use the same value as the added value in the File Table)
   • DiskPrompt: LABEL
9. In the top menu, choose Transform -> Generate Transform... (Save in the same folder as the .msi file and .xml).

Now you should be able to deploy the application with a valid license with your favourite deployment software:

msiexec /i ToadforOracle_GA_13.xxxx.msi TRANSFORMS=ToadforOracle_GA_13.xxxx.mst /qn /norestart
