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

[Thomas_HP_Ret]

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.

Thanks Freidhelm for the effort and thorough response but I am already aware of and using the work around temporary fix via the manual activation key.  Its cumbersome but at least it's there and it works, I'm thankful for that.  Echoing another user's thoughts:  Is this intent for how the program works going forward? I've received no communications to that effect.

The fundamental problem with Express normal start-up is something has broken the 'phone home' communication link between the license server routine on this laptop and the license server at PTC.  For Express or its big brother CE Direct Modeling to run requires a periodic 'ping' from the device to a license server at PTC and the resultant response.  If that fails the program won't run.  Meaning there is an unresolved issue with the license server at PTC or something has changed the settings on this laptop.  I do not have the IT skills to fix this, was hoping someone could help me do that.  I've changed my password, uninstalled and reinstalled the program, both to no avail.  Suggestions?

First of all, I would like to ask why you only wrote >Creo Modeling Express no longer starts.
and not additionally that you are already getting the 72 hour license ?
This made me think that you could not start at all.  🙄
Then I could have saved myself the work and written the following directly to you.

>Suggestions?
Yes, forget it and stop looking for an other solution!
Keep working with the 72 hour license, there is no other way.
PTC will fix it one day, but it's at the deepest bottom of the priority list.

The problem is, that we  (at least I) can't even start the program, because the activation is failing.

(the activation code is invalid) while I just requested it. copy/paste ctrl+a/ctrl+c/ctrl+v doesn't make any difference. I cant find any thing beyond this blog...

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.

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

Unfortunately, you misunderstood me.

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 is incorrect and I can't use it.

No matter how many new activation keys I receive, each key is always incorrect and a window appears with the message "the key is not correct".

Question:

Is this 72 hour activation only once per account?

↓↓↓Confirmed↓↓↓

"I create a new account, and i get another 72 hours for activation.

But it seems so ridiculous to create a new account for every 72 hours activation..."

[Kotom-Eng]

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
