Has anyone had success setting up the 2004 licensing (FlexLM 8.3c) on a Windows NT box running service pack 6a serving both 2002 and 2004 product licenses. I am unable to access either the 2002 or 2004 licenses after upgrading with the files combined. Then I removed the 2002 entries from the license file and tried to start Autocad 2004 on a client machine and it won't hit the LM either. I stopped and removed the service before installing the new version of FlexLM and I don't receive any errors upon starting the service. I have uninstalled and reinstalled the 2002 FlexLM version and it works fine. Any ideas would be appreciated.
