I would like to note that I have never encountered such an issue with NUMECA software before, and this has been an unexpected challenge for me.

I have suddenly received this message when I opened Fineopen ""

host VDH

wout — Fri, 17 Feb 2023 17:06:14 GMT

Dear

In the beginning of October, I received a student license for the marine package. I have been using it frequently since then but today I wasn't able to use it anymore.

When I used the admin tool to try to solve this problem, it gives an error mentioning that the host VDH (vendor defined hostID) can't be found.

The diagnostics give error for: NUMECA activation server reachable, license file(s) validity, windows registry

the diagnostics show failed for: license server(s) reachable

Could you please help me to solve these errors?

kind regards

License check has failed

Torki — Tue, 07 Feb 2023 16:30:51 GMT

Hello,

I wasn't able to open Omnis today in reason of a failed license check. As you can see in the first screenshot , the program ask me to reactivate my license. I tried to do it again with the admin tool, but I got the error in the last screenshot. Therefore I thought of running the diagnostics with the Admin Tool (second screenshot) and asking for help in this forum.

I would be really thankful, if you could help me with this.

Kind regards,
Youssef.

Problem with activating OMNIS in Admin Tool

edmem — Tue, 13 Dec 2022 15:45:39 GMT

Hey,

I have the problem that I can't activate OMNIS via the license file that was attached to my email. It always fails and then the error "License Server Error" pops up. It says: "Could not connect to the server @... but the ping succeeded. Reason: the daemon(s) ['numeca'] are down on the server @... "

I saw a post with a similar problem but it didn't work out in my case.

Unable to access installation file on OneDrive

The account needs to be added as an external user in the tenant first. Sign out and sign in again with a different Azure Active Directory user account.

The Microsoft Account used is connected to the correct student E-Mail address. Access was requested both via the university and a private network but resulted in the same error.

As a Browser I used Mozilla Firefox.

I hope this error can be resolved.

Hey,

I installed OMNIS 5.2 on my Laptop. I've got no problems with the license activation, at least it shows "Success" at the bottom left. But every time I try to start the program the icon of OMNIS appears for a few seconds, but after that it closes itself. Do you have any suggestions what might gone wrong?

best regards,

RE: Troubleshooting installation of free student license installation (with license text file)

Durai12 — Tue, 01 Nov 2022 13:45:55 GMT

Hello

I am trying to activate omnis. I have followed the steps as show, and when I try to activate the software with the license file I am getting an error saying requested daemon(s) are down, but the ping succeeded). I tried to get the startup log but I got an error saying "access denied".

OS : Windows 10

Software : OMNIS 5.2

Any ideas on how to solve this?

Troubleshooting installation of free student license installation (with license text file)

Colinda — Thu, 27 Oct 2022 12:53:34 GMT

When requesting a free student license, a license text file is provided (or 2 in the case of Fine Marine).

Go to the Admin Tool as installed together with the product of your choice (Omnis v5.2 or Fine Marine v10.2-2).
In the License management section select Activate from license file(s).
Select the license file(s) as received by email.
Click on Activate.
The License server tab in the same section should indicate that the server is up.
- yes: the software should start. If that's still not the case, go to the Diagnostics section and check what else could be wrong.

If all this does not help, please make a new forum post with the description of what happens in your case in the above steps.

Mention also:

the OS version,
the software version,
The startup log when launching the software through command line:
- Linux: omnis5.2 -print > startup_log.txt
- Windows: cd "c:\Program Files (x86)\NUMECA Software\Omnis 5.2" and then: omnis.bat -print > startup_log.txt

      Then share startup_log.txt

Screen captures may also help to illustrate the situation and get a fast response. Make sure not to show confidential information in the screen captures though.

License via the ip of my university

sriluta — Tue, 12 Jul 2022 13:33:26 GMT

Hey,

Troubleshooting installation of free student version (using activation ID)

Colinda — Tue, 05 Apr 2022 14:43:05 GMT

Until September 2022 the free student license was provided through an activation ID.

As of September 2022 a license text file is provided and hence this discussion is no longer relevant.

This activation ID can be entered at first launch after installation or in the Admin Tool.

It can be used only once. When making changes to the computer configuration (including changes in the OS) may damage the activation => de-activate in the Product (de-)activation tab (in the Admin Tool).

If the software does not start, check the following:

The OS is supported (see the system requirements in the documentation)?
In the Trusted storage tab in the License management section of the Admin Tool a line should be visible confirming the successful activation of the free student version.
- yes: go to the next check
- no: go to the Product (de-)activation tab and try to run the activation with the ID received by email. ATTENTION: the activation ID can be used only on one
The License server tab in the same section should indicate that the server is up.
- yes: the software should start. If that's still not the case go to the Diagnostics section and check what else could be wrong.
- no: If it is not running select "activate from license file(s)" and use the generic license file "c:\Program Files (x86)\License_management\any.lic". If you have limited permission on your machine, It is possible that you need to redo this step after a reboot.

If all this does not help, please make a new forum post with the description of what happens in your case in the above checks.

Mention also:

the OS version,
the software version,
The startup log when launching the software through command line:
- Linux: omnis5.2 -print > startup_log.txt
- Windows: cd "c:\Program Files (x86)\NUMECA Software\Omnis 5.2" and then: omnis.bat -print > startup_log.txt

      Then share startup_log.txt

Screen captures may also help to illustrate the situation and get a fast response. Make sure not to show confidential information in the screen captures though.
