Question

Creo Modeling Express won't start, doesn't activate, prompts for unknown proxy server

After working well since initial download on 7/30/23,  Creo Modeling Express no longer starts.  Instead a pop up dialogue prompting me for email and password to Activate comes up.  After entering my e-address and password. and selecting 'Activate' I get a second dialogue saying:  Connection failed.  For Modeling Express to automatically activate it requires access to the internet.  Please check if a proxy has to be specified and enter your company's proxy server details so that activation can proceed.  I'm merely an individual with a laptop, there is no proxy server.  My internet connection is fine and I have a basic PTC account.  How can I fix this and why did it happen?

I selected the link, there is no actionable content there.  Possibly because I have only the basic account required to use Express.  Below is what I get.

This problem exist from many years clearly it's not an issue. Never worked well and work only randomly. I have used Modeling Express for some simple parts and now the same issue. They want only big customers not individual, I suppose but it's clear.

    I was able to copy this activation key, which is valid for 72 hours, and paste it into the Manual Product Activation window to use it.
    The first time, I was able to use it for 72 hours without any problems.

    After 72 hours have passed, I want to use it again, so I do the same thing, but this time a window appears saying that key is incorrect and I can't use it...

    Greetings

    If I understand correctly, you are attempting to use the same key for a second 72 hour session. That will not work, you must obtain a new unique key for each 72 hour session. Go back through the process to obtain a new key and everything will work as advertised.

    Hope that helps, Thomas

    No, the 72 hour activation is not only once per account. You can get several activation for every 72 hour with the same login.

    Try it in 72 hours with your new account.

     

    The problem with the first account is elsewhere. How do you get the activation key? Two possibilities:

    - By the panels given by Modeling.during start

    - With this link https://www.ptc.com/appserver/securePeModeling/peManualLic.jsp
