Incorrect version of the Xheo DLL loaded

Problem

A message box is displayed when Iron Speed Designer starts explaining that:

An incorrect version of the Xheo .dll has been loaded for this program.

Solution

When this happens, it is almost always due to a conflict with an older version of the Xheo.Licensing.dll which has been installed in the Global Assembly Cache (GAC) (\windows\assembly folder) by another program.  To resolve this problem:

Step 1:  Uninstall the other program using Xheo.Licensing.dll.

Step 2:  Activate Iron Speed Designer with your product key.

In some cases, you can use the Microsoft Gacutil utility to remove the Xheo entry from the GAC.  Instructions for Gacutil can be found at:
