Installation Requirements:
Installing XLSurfFit on Windows 7, 8, 10 or Server 2008:
  • Uninstall the existing version of XLGrapher, if any. Note that XLSurfFit depends on and thus includes all features of XLGrapher.
  • Download and run XLGrapher v4.8.0 installer (which will install XLSurfFit as well).
  • If you are installing XLSurfFit on a Standard user account, the installer will ask you to enter an administrator’s user name and password. After successful installation, you will be automatically returned to your Standard User account.
  • Note that the installer only installs XLSurfFit for the user account currently logged in. If you wish to install XLSurfFit for all users on a single machine, repeat the above steps.
Activating XLSurfFit on Windows 7, 8, 10 or Server 2008:
  1. Start Excel as an Administrator. To do that, click Windows Start button, type Excel. Microsoft Excel xxxx shortcut shall show-up. Hold down Ctrl+Shift keys and then right mouse click on Microsoft Excel xxxx, choose Run as administrator to start Excel.
  2. Under ThreeDify XLGrapher add-in menu within Excel, select License Manager and then select “3D Graphing or SurfaceFit” as the module name, and then hit Activate button.
  3. Copy and paste your XLSurfFit Product Key provided by ThreeDify.
  4. Restart Excel as usual and both XLSurfFit and XLGrapher shall be activated.

Note that another way to start Excel as an Administrator at Step 1 above is to right mouse click on any Excel shortcut (from Windows Start menu most likely), choose Properties, switch to Compatibility tab and set “Run this program as an administrator” checkbox to “on”. If that is done, then you need to set this checkbox “off” before performing the last step above.
