File Content Extraction 25.3
Filter SDK .NET Programming Guide

# Software Dependencies

TIP: This section describes software that you, or the end user of your application, must install alongside File Content Extraction. For information about third-party software that is included with File Content Extraction, see Third-Party Libraries.

To run File Content Extraction on Windows requires the Microsoft Visual C++ 2019 redistributables to be installed. The redistributables are provided in the `vcredist` folder of the SDK but you can download the latest installers from Microsoft to get the latest security, reliability, and performance improvements.

Some File Content Extraction components require specific third-party software:

- The Filter .NET API requires .NET 6.0 or later.

- Outlook 2002 or later is required to process Microsoft Outlook Personal Folders (PST) files using the MAPI-based reader (`pstsr`). The native PST reader (`pstxsr`) does not require Outlook.

  NOTE: You must install an edition of Microsoft Outlook (32-bit or 64-bit) that matches the File Content Extraction software. For example, if you use 64-bit File Content Extraction, install 64-bit Outlook.

  If the editions do not match, File Content Extraction returns `Error 32: KVError_PSTAccessFailed` and an error message from Microsoft Office Outlook is displayed: `Either there is a no default mail client or the current mail client cannot fulfill the messaging request. Please run Microsoft Outlook and set it as the default mail client`.

- Lotus Notes or Lotus Domino is required for Lotus Notes database (NSF) file processing. The minimum requirement is 6.5.1, but version 8.5 is recommended.
