Hello,
Did you install it via Get programs? Please try to restart the computer and if it still requests to enter the license server name, then create the system environment variable:
Name: FLEXLM_TIMEOUT
Value: 2000000
Also check if the following system env. variable is created or not:
Name: ADSKFLEX_LICENSE_FILE
Value: @DALACADLIC.NA.XOM.COM
About system environment variables in Win 7 you can find an article here.
Let me know how it worked.
