Hi, the problem is as the title states. I saw another post explaining the same problem but with Creo 3.0. I'm trying to download Creo 4.0 but it's giving me an invalid file or format when trying to install license. Tried opening the file but was empty. How do I solve this? Thanks

I guess the problem is related to non-supported network card.
Please open Command Prompt window, launch ipconfig /all > ip.txt command and upload ip.txt file. I will check your ip.txt file and suggest you to disable suspicious network card.
I have a similar issue. When i go into creo, it states that "License request failed for feature" and kicks me out of the software.
the error message tells you that creo is not able to find the proper license file.
Please attach a picture of error window (enlarge it to show the whole message).
I can't open ipconfig, for some reason.
I tried what you said in the other threads about deleting CREO (I didn't have it installed to begin with) and deleting the license file from the folder. Still didn't work.
I tried using advanced license entry to use the other network cards, they all have the same problem. I also tried disabling all my firewalls and VPN. Still not working.
Then I tried doing just the licence setup, still the same error with all 3 network cards.
Got it. Here's what I did before it finally worked:
I didn't try all the other possible iterations between these steps.
Anyways, it worked and I hope this helps others.
Thanks for the solid advice @MartinHanak
