I just had a license file generated for a couple of seats of 2004 to run along with our 2002 seats. I added the license info to our existing file and reread the file in FlexLM. I cannot get 2004 to open on the workstation (error 1.5-18 no valid license). Looking at the log on the server I see the following: Unsupported: "42600ACD_2004_OF" (PORT_AR_HOST_PLUS) License server does not support this feature (-18, 327). We are running version 8.3c of FlexLM. Can you help me please.
