Thank you for the reply, however I am still unsure how to fix this issue.
1) I've already uninstalled Nevron evaluation version....I don't have a license manager. Do I need to install just the license manager to remove the license? If so, where can I download it?
2) If I have to do it programmatically, do you have sample code for removing the reg key? The link you sent seemed to only have code for adding a license key.
3) If you just let me know the reg keys to remove I can do that manually.
