Hello, I've done many stand alone license installs and have never seen this error before... Creo Academic Edition Standalone Licensing You have already registered for this the maximum number of times.
I've completely removed/uninstalled the old Creo 2.0 but can't get past this error from the licensing file generation page at: http://www.ptc.com/appserver/lm/programs/licensing_programs_v.jsp
I've tried a couple of times to get my expired Creo back up but no luck. ??

Note: I am not sure if PTC responds quickly ...
