Q1: How can I determine if I have the latest version of an Accusoft Pegasus control?
Please download the PegConnect utility program from the following link: PegConnect
or reference the Latest Builds page.

Q2: What is the difference between the 2 editions of the PDF Xpress v3 product (Reader and Professional)?
Please refer to the descriptions below:

Reader Edition
This edition allows application developers to read PDF documents (including the associated annotations and bookmarks), render pages, and extract content from PDFs. (The Reader Edition contains a subset of Professional Edition features.)

Professional Edition
This edition provides application developers the ability to create PDF documents and modify the PDF content, plus all of the Reader Edition features.

Q3: What are the new features of PDF Xpress v3?
Please refer to the information on the following page.

Q4: What are runtimes? How do I pay for them?
Licensing requirements for PDF Xpress are documented on the PDF Xpress pricing page.

Q5: What version of PDF files does PDF Xpress v3 support?
PDF Xpress v3 will open a well-formed PDF document of any version, if a valid user- or owner-password is provided, as required. The PDF specification is designed to be backwards compatible. Even earlier versions of Adobe Reader should open the newest PDFs; unknown features are typically ignored. Operations such as printing to EPS, rendering, etc are governed by the permissions associated with the password (if any) used to successfully open the PDF.

PDF Xpress v3 will create PDF v1.6.

PDF Xpress v3 will modify an open PDF document if permissions associated with the password used to open the document permit changes can be made.

Q6: What is XFDF and how does the schema import and export process function in PDFXpress v3?
XFDF (XML Forms Data Format) is an Adobe-created format for representing form data and annotations.

PDF Xpress created XFDF will contain only data for PDF Xpress supported annotations as follows in the chart listed below:

Q7: How do I distribute my application?
Please note: You must have received unlock codes in order to distribute applications. These are received when runtimes are purchased. If you have not received them please Contact Sales.

1) If you are using the .NET interface you must call the UnlockRuntime method in the Licensing class where the application begins and pass the unlock codes as the parameters. For example:

PDFXpress3.Licensing.UnlockRuntime(1234,1234,1234,1234);

2) If you are using the ActiveX control you must call the UnlockRuntime method where your application begins and pass the unlock codes as the parameters. For example:

PDFXpress3.UnlockRuntime 1234,1234,1234,1234

Q8: What DLL's do I need to distribute with my application?
1) If you are using the ActiveX interface please distribute the following DLLs:

     PegasusImaging.ActiveX.PDFXpress3.dll - ActiveX component - ActiveX Control for PDF document creation and text recognition

Please Note: You must register the PegasusImaging.ActiveX.PDFXpress3.dll via your installation program or manually via the regsvr32.exe utility.

2) If you are using the .NET interface please distribute the following DLL:

     PegasusImaging.WinForms.PDFXpress3.dll - .NET component - Control for PDF document manipulation.
