IsEngineInstalled # get (CodecsPdfOptions)
| Value | Description |
|---|---|
| true | To indicate the LEADTOOLS PDF Engine Runtime files are installed. |
| false | To indicate the LEADTOOLS PDF Engine Runtime files are missing. |
Use this property to determine if the LEADTOOLS PDF Engine Runtime files (Leadtools.Pdf.Utilities.dll) are installed on the system.
The value of this property is used only when Leadtools.Pdf.Utilities.dll is used by the application. For more information, refer to Implementing PDF Features.
