Hello Gerald,

Uninstall the program and then download the latest installer from the "download" section of your answers.websitex5.com profile and install it. If the issue persists try to uninstall the .NET3.5 Framework and then use this cleanup tool: http://cid-27e6a35d1a492af7.skydrive.live.com/self.aspx/Blog_Tools/dotnetfx_cleanup_tool.zip

Once the cleanup tool has finished reinstall the .NET 3.5 Framework: www.microsoft.com/de-de/download/details.aspx?id=25150

Once the framework is installed again try to open the program again and register it.

Please let me know if this helps.
