Software Dependencies

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

To run OCR and RMS decryption on Linux, KeyView requires the versions of libstdc++.so.6 and libgcc_s.so.1 from the following GCC versions:

  • Linux x86-64:  GCC 12.2 or later

  • Linux ARM: GCC 5.5 or later

For your convenience, these are provided in the redist folder of your KeyView installation.

NOTE: If you are running KeyView out-of-process then the kvoop executable must be able to link to libstdc++.so.6 and libgcc_s.so.1.

  • If these are installed in a system folder, like /lib64, KeyView will find them automatically.
  • If you prefer you can add the path of the folder containing these libraries to the environment variable LD_LIBRARY_PATH.

If you are running KeyView in-process:

  • If your application is already linking to libgcc_s and libstdc++ from GCC 12.2 or later, KeyView will use them as well and no further action is needed.
  • If your application is linking to earlier versions of libgcc_s and libstdc++, OpenText recommends that you upgrade those binaries to those from GCC 12.2 or later.
  • If your application is not linking to libgcc_s and libstdc++ you must ensure those binaries are available in the same way as described in the instructions, above, for running KeyView out-of-process.

If older versions of libgcc_s and libstdc++ are provided (but at least those from GCC 4.8) then most features will continue to work, but Optical Character Recognition and RMS Decryption will not.

Some KeyView components require specific third-party software:

  • Java Runtime Environment (JRE) or Java Development Kit (JDK) version 7 to 17 is required for the Filter and Export Java APIs.

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

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

    If the editions do not match, KeyView 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.
