Product key activation fails to register

Problem

When activating a product key, Iron Speed Designer accepts the product key as valid but then returns to the activation screen, remaining stuck at that point.

This is usually caused by an incorrect version of the Xheo licensing DLL installed on your system.

Solution

The Xheo DLL may have been installed in the Global Assembly Cache (GAC) and should be removed from the GAC.

Step 1:  Using Windows Explorer, go to your Windows folder (usually c:\windows) where you should find a folder named “assembly”.  Open this folder and look for an entry for “xheo.licensing”.

If you find this entry, that is the cause of the activation problem.

Step 2:  Open a Command Prompt window.

Step 3:  In the command prompt window, go to the system folder where your .NET framework software is installed, usually:

C:\Windows\Microsoft.NET\Framework\v2.0.50727

Step 4:  Run this utility to clear the GAC.

gacutil.exe /u Xheo.Licensing.dll

Step 5:  If this does not eliminate the problem, then the old Xheo software has most likely been installed by some other software which also uses it.  You must remove that other software to get rid of the old Xheo software.

Search your file system for Xheo.Licensing.dll and delete it if no other program uses this Xheo file.
