KeyView 23.4

# 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 KeyView OCR, source code identification, 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 5.4 or later

- Linux ARM: GCC 5.5 or later

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

NOTE: If you are running KeyView out-of-process then the `servant` and `WKOOP.exe` executables 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 5.4 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 5.4 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 PDF Export, 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 in the ExportSDK for outputting to raster graphic images on non-Windows platforms in the Export SDK.

- 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.
