Installing the OSS ASN.1 Tools for C#

Applies to: ASN.1/C# 5.0

Prerequisites for the OSS ASN.1 Tools for C# v4.0 and later:

  • Microsoft .NET Framework 3.0 or later.
  • Microsoft C# 3.0 with Microsoft Visual Studio 2008 or later (Visual Studio is recommended but not required).
    NOTE: Pre-4.0 versions of ASN.1 Tools for C# required .NET Framework 1.1 or later, and Java runtime 1.4.2 or later.

The License Key: A valid ossinfo license authorization file is required to successfully install and run the OSS ASN.1 Tools Compiler. This file is provided by email at the time of purchase or trial and contains specific information about your license and the system on which you are authorized to run the program. If you need help locating your ossinfo file, contact customerservice@oss.com.

  1. You must have administrator privileges on the system where the OSS ASN.1 Tools for C# will be installed.

    Download and run the installation executable for your license and platform. Follow the on-screen instructions. The install program prompts you for the location of the ossinfo file. Specify the folder location using the Browse button or allow the program to search for the file. Once the license key is found, it is validated and copied to the \Program Files\OSS Nokalva folder. When installation is complete, launch the program from the OSS ASN.1 Tools for C# program menu. If you are upgrading/migrating from a pre-4.0 release, read the Migration Guide included under the Documentation menu.

    By default, the installation folder is
    \Program Files\OSS Nokalva\asn1csharp\<platform name>\<version number>
    However, the installation program gives you the option to select a different folder, if you wish.

    ASN.1 Studio, a powerful IDE, is packaged with the OSS ASN.1 Tools for C#. The default installation folder for ASN.1 Studio is
    \Program Files\OSS Nokalva\asn1studio\<platform name>

    NOTE: If a Windows 32-bit (x86) version of the Tools is installed on a Windows 64-bit (x64) system, the default installation folder will be
    \Program Files (x86)\OSS Nokalva\...
  2. NOTE: If you are installing a 30-day trial version of the OSS ASN.1 Tools for C#, the following exceptions apply:
    • The license authorization filename is ossinfocstrial.
    • The default installation directory for the trial is
      C:\Program Files\OSS Nokalva\asn1csharp\<platform name>.trial\<version number>.
    • Use the OSSINFOTRIAL environment variable to point to a non-default location of the ossinfocstrial file.
  3. Select Introduction from the program menu to read about what's new in this release, how to access samples, runtime choices, and more.

    Access documentation and information on getting started with ASN.1 Studio from Help on the ASN.1 Studio main menu.
