You got a license file in registered mail id , just put the file in license verification in creo and make sure that internet connection is working…
Or You can Download the crack version from getintopc.com
Can you share more information like what version of CREO have you installed? and what type of account you have registered as like Trial Package, Essential Package, Advanced Package, Premium Package.
If possible can you share a screenshot or error message to get a better understanding of the issue?
