i had installed student version of creo 220.127.116.11 after installing my license successfully I got sw license file in email. I had pasted in C:\ProgramData\PTC\Licensing
while my internet connection is connected creo parametric application was opening with out warning message list but when i had disconnected my internet connection i was unable to open creo application it was showing warning message list. again i had connected my internet connection but it was not opening.
Solved! Go to Solution.
during installation you were connected to Internet via network card with physical address 3A-C1-DB-D1-CF-10. Creo installer detected this physical address and used it for license generation.
It look like physical address 3A-C1-DB-D1-CF-10 was assigned dynamically and does not exist anymore. Therefore Creo cannot find it and does not start.
To see network card physical addresses, you can open Command Prompt window and run ipconfig /all command.
What is the solution for this?
I am sorry I can't provide simple solution, because I do not know, how you are connecting to Internet. Ask some experienced friend.
General advice - you have to configure your PC to connect to Internet via Ethernet or WiFi network card. These network cards have fixed physical addresses.
After fixing Internet connection you have to uninstall/install Creo 6. Do not forget to empty C:\ProgramData\PTC\Licensing directory !
If i have not permanent internet connection then i can't use it? Means
you can use Creo "offline". But Creo must "see" the network card for which the license is generated.
