    • The 'Install for All Users' options enables all users of the current machine to use fxRender without separately having to install and register it. This option requires Administrative Rights for the computer, and will require an Admin Password if you are not already logged in as the Administrator.

    Toolbar
  • NetworkTo activate your copy of fxRender and start the free trial the computer needs to be connected to the Internet. If you see the Network button in the toolbar then fxRender is having difficulty connecting to the network. If your internet connection is working normally (test using Internet Explorer), then select this button to configure your network settings.

    Proxy Configuration

    fxRender needs to be able to connect to the Internet to:

    • Activate and Register the product, which includes download a valid licence key.
    • Generate equations using the our online LaTeX engine, to generate 100% LaTeX compliant output.
    • Connect to our online rendering engine (see CodeCogs Equation Editor) to publish equations online.

    fxRender will try to automatically find an external connection to the Internet. However, for better speed, we recommend you configure the settings according to your network (a chat to your IT department or system administrators might be needed).

    Making Changes

    • You can always make changes to Network Settings by clicking on network which appears under the 'help' drop-down menu on the toolbar. If there is no current network connection you will see a larger button on the toolbar.
    • The default is 'Use IE proxy settings', which typically finds a connection - this leads to slower connection performance, so should be avoided if possible.
    • If you are connected directly to the Internet, then the fastest connection is 'No Proxy'.
    • If you are within a company and you know the name of the 'Proxy server' (ask IT), then 'Manual proxy setting' is best.
    • If your corporate network is configured correctly, then 'Use proxy auto-detection (WPAD Protocol)'. This should automatically find a PAC file with appropriate proxy settings for your location. PAC files are ideal for users who are routinely moving about.
  • RegisterIf you see the Licence button in the toolbar, then fxRender has been activated and you can start using it for the trial period of 15 day. Thereafter you'll need to press this button and register the product.

Trouble Shooting

If you are installing fxRender on a machine without Internet access or with a pecular configuration then our standard installer is unlikely to work. Please ensure the additional components (listed below) are available on your system and download from the right the installer suited to your needs.

The following additional components must be installed for fxRender to function:

  • Microsoft .NET Framework:

    Microsoft .NET Framework

    The Microsoft .NET Framework (pronounced dot net) is a software framework developed by Microsoft that runs primarily on Microsoft Windows. The .NET Framework is intended to be used by most new applications created for the Windows platform.

    It is essential for fxRender to work, as it provides functionality for the user interface, data access, cryptography, numeric algorithms, and network communications.

    The fxRender installer should automatically install this. However, if you need to install this manually, then the follow minimum versions are needed:

  • Excel .NET Programmability Support must be installed to enable Primary Interop Assemblies (PIAs) for your version of Excel. If during the original installation of Microsoft Excel this option was deselected or Excel was installed before the .NET Frameworks, then follow these steps:

    Excel .NET Programmability Support

    • Open the Control Panel (Windows Start - Control Panel)
      • If you are in 'Category' view, select 'Programs'
    • Select 'Programs and Features'
    • Find 'Microsoft Office 2010'
    • Right click and select 'Change'
    • Select 'Add or Remove Features':
    • Select the .NET Programmability Support, and enable 'Run from My Computer':

    Alternatively the PIAs can be downloaded and installed from Microsoft:

  • Math Cambria Font (Important if you using Windows XP and Excel 2003)

    Math Cambria Font

    fxRender requires the Microsoft Math Cambria Font to generate mathematical symbols offline. This is standard part of Windows Vista, 7 and 8, and is included with Microsoft Office 2007 and later. On other configuration you may need to install this fix:

  • Installing on Excel 2003

    Installing fxRender for Excel 2003

    Microsoft Excel 2003 has a security feature called CASPOL that requires administrator permissions to change and is required for fxRender to work fully. CASPOL has always been a nightmare for developers, so Microsoft dropped its use in later versions of Excel.

    Thus you can only install fxRender for Excel 2003 if you are an administrator for your machine.

Uninstall

Should you need to uninstall fxRender you can either:

  • From the 'Start Menu', select 'Control Panel'
  • Depending on your view, select either:
    • 'Programs and Features'
    • 'Uninstall a program' under 'Programs'
  • Find the main 'fxRender' package in the list install packages.
  • Right click and select 'Uninstall'.
  • Repeat the above if you have still have over version of fxRender listed.
