I discovered that if I downloaded the Xceed Components from the What’s New link, it included some older DLL’s. I changed the references within my project to use the 4.9 version dll’s and the trial key started working.
Update…I found a download for the Xceed Components by following the “What’s New” link. Within the 6.0 notes, there was a download link. After I installed this, I was able to get a Trial Key to add to my code, however I got an exception stating:
The license key used to license this Xceed product is not in a valid version range. To unlock this assembly, please make sure that you are using a valid or up-to-date license key.
