Hello PTC Academic Support,
I’m a student trying to run Creo Parametric and my node-locked student license is failing with:
• “License request failed for feature … license.dat: (-9) Invalid host.”
• When I run reconfigure.exe and enter my product code, I get: “You have reached the maximum number of license requests available for your product type.”
Could you please reset my student license activations or reissue a license tied to my current host ID?
Details:
• Product code originally used: BK120908EDUNIVERSITYED
• PTC Academic account email: poor0041@umn.edu
It would work when I would try to reconfigure it but now I have run out of license. but it only doesn't work on EDroam wifi it seems.
• Computer name: Nicks-Laptop
• OS: Windows 10 (Version 10.0.26100.6584)
• Current active adapter MAC (host ID): 3E-C3-27-C4-FE-F2
• License file HOSTID currently tied to: 32-DA-63-A1-9A-2F
• Error dialogs: “(-9) Invalid host” in Creo; “maximum number of license requests” in reconfigure.exe
• License files path: C:\ProgramData\PTC\Licensing\
I can attach my current license.dat and a screenshot of the error if helpful.
Thank you!
