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...

    You can't use a key twice.

    A new one has to be created.
