Anybody seen this before? Some urgent help would be desired

I am an undergraduate student at Jiangsu University, China. I have successfully completed student verification and obtained an Altair Student Edition license for Simcenter PSIM 26.1.

In July 2026, I reinstalled Windows on the same physical computer. Unfortunately, I could not deactivate my previous license activation before reinstalling the operating system.

Since then, I have been unable to reactivate my student license.

1. License activation error

When I try to activate my license through Altair License Utility, I receive the following message:

"This license was already activated using different HostIDs."

2. PSIM licensing error

When I launch PSIM 26.1, I receive:

• Error Code: -29
• Requested CT/TTF license not found for given customer ID
• Features affected: PSIMPowerSupplyFeature and PSIMPowerSupply

My current HostID is A428_B701_FDA5_004B.

I have already contacted the support email addresses I could find, but received an automatic reply stating that the mailbox was decommissioned and no support case was created.

I previously posted about this issue in the community, but I have not received a response yet.

Could an Altair representative please help me reset or release the previous license activation associated with my old HostID? I am using the same physical computer and would like to reactivate my existing student license.

I would also appreciate help investigating the Error Code -29 issue.

I can provide screenshots, my license activation details, and any additional information privately if required.

Thank you for your time and assistance.

Best regards,
Bo Xun Ye
Jiangsu University, China

Thanks,

I am an electrical engineering student at Kwangwoon University in South Korea. I previously used Altair PSIM 2025.1 with a free Student Edition license.

I am currently unable to use PSIM due to licensing issues.

1. Student License Renewal Issue

• My Student Edition license was issued on September 29, 2025.
• In Altair One Marketplace, the "Renew License" button is missing.
• Only the "Get License" button appears, which displays my old activation key.
• Under Managed Licenses → On Prem, the license shows "Activation Allowed: 1" and "Activation Left: 0".

2. PSIM License Errors

When launching PSIM 2025.1, I receive the following errors:

• PSIMPowerSupplyFeature – Feature not found (Error 9)
• Requested CT/TTF license not found for given customer ID (Error -29)
• Connection to the license server is lost.

I also tried activating my existing license key again through Altair License Utility, but received:

"Error activating license: License already exists in license store."

I checked the existing .lic file but could not find any PSIM-related feature names.

3. Software Download Issue

Additionally, the "Software Downloads" tab is missing from the Simcenter PSIM page in Altair One Marketplace. Only "Info" and "Try and Buy" are available.

Could you please help me with the following?

1. Restore or enable the "Renew License" option for my Student Edition account.
2. Verify that my license includes the required PSIM features and issue a corrected license if necessary.
3. Confirm how I can access the Simcenter PSIM Student Edition installer.

I have attached screenshots showing the licensing errors and account status.

Thank you for your assistance!

I activated my HyperMesh Student Edition license on my previous computer, but I no longer have access to that computer. On my new computer I get the error:

"Error activating license: This license was already activated using different HostIDs."

Could you please deactivate the license from my old machine in Altair One so that I can reactivate it with the same key on my new computer?

Altair One account email: ayazb22@itu.edu.tr
Software: HyperMesh (Student Edition)

I can send the license key by private message if needed.

Thank you.

I can’t see the download button, I’m only able to select “try and buy”.

I am a student using Windows, and I have already generated my Altair Student Edition license activation key. However, when I open HyperMesh in the Altair One Marketplace, the “Software Downloads” tab is missing, so I cannot download the installer.

I have followed the student license procedure. Could you please check my account's Student Edition download entitlement and help me access the official HyperMesh Windows installer?

Thank you for your help.

I'm having trouble installing the Inspire software with the student license. I followed the provided tutorial to activate the license without any issues. However, the "Download" button doesn't appear on the software page in the Marketplace, even though I logged out and back in as instructed in the tutorial.

Could you please help me resolve this problem?

Thank you in advance for your help :)

I have generated and received my Student Edition on-premise activation key. However, when I log into Altair Marketplace under the Student Edition Bundle, the "Software Downloads" tab does not appear for Simcenter HyperMesh or Simcenter OptiStruct (only "Info" and "Try and Buy" appear).

I have already tried signing out/in and using incognito mode. Please sync the download entitlements for my account.

Registered Email: [nm2301ed09@rguktn.ac.in]

Please reset/deactivate the previous activation so I can reactivate on this PC. My Altair One account email is: ahmed.baklouti@enim.u-monastir.tn. I can send the activation key privately if needed.

I have urgent university work that depends on PSIM, so I would really appreciate a quick reply. Thank you.

Hello Altair Support Team,

I am currently using HyperWorks 2025.1 with a free Student Edition license obtained through my university email address. My license was renewed on September 4, 2026, and is valid until September 4, 2027.

I am experiencing two issues:

1. Software Downloads tab missing

When accessing Altair One Marketplace, I can see the Student Edition Bundle and its available applications, including HyperMesh and OptiStruct. However, the "Software Downloads" tab is missing for every application. Only "Info" and "Try and Buy" are displayed.

I would like to download and install the latest available Student Edition, but I cannot access the installers.

2. OptiStruct license error

I can successfully execute linear static and normal modes analyses in OptiStruct 2025.1. However, when attempting to run a Modal Frequency Response analysis, the solver stops with the following errors:

• Feature not found: HWOptiStruct / OptiStruct
• Requested CT/TTF license not found for given customer ID
• No Available License

Both the successful analyses and the failed frequency response analysis were executed using Altair Compute Console.

I have already verified that my Student Edition license is active and that the environment variable ALM_HHWU is set to F.

Could you please help me verify my Student Edition download permissions and determine why OptiStruct cannot obtain the required license for the frequency response analysis?

Thank you for your time and assistance.

I'm trying to install hypermesh on another pc, using the same altair one account and license, is this related?

I am trying to renew my academic student license for Hypermesh, but I am completely blocked from logging into the Altair One Marketplace due to the ongoing site-wide technical outage and Cloudflare access block.

Since the marketplace is down and my current license has expired, I am unable to access the standard renewal form or download the updated activation keys for my coursework. What can I do in this situation?

Some member are getting Error 15 and -29 when opening the program. Download work fine and the Altair License Utility says we are authorized to use Managed Licensing.

I tried to configure the ALTAIR_LICENSE_PATH but I am not sure what server Id to use. I don´t know where to get it.

I am a researcher at Northeastern University, China. I have registered an Altair One account with my university email but cannot access https://altairone.com due to Cloudflare blocking. I have tried different browsers, clearing cookies, switching networks, and mobile hotspots - all failed.

Could you please:

1. Help me obtain my Student Edition License Key
2. Provide a direct download link for HyperMesh Desktop Student Edition and Inspire Form

My registered email: csliu@mail.neu.edu.cn

Thank you.

I am an existing PSIM Student Edition user.

My PSIM Student Edition license expired in June 2026, and I am trying to renew the license.

However, when I try to access Altair One (altairone.com), I receive the following message:

"Sorry, you have been blocked. You are unable to access altairone.com."

I have already tried different browsers, devices, internet connections, and IP addresses, but the same Cloudflare block page appears every time.

My Altair Community account is working normally, and I have already completed the email verification.

Cloudflare Ray ID: a4296ddcac44c02f

In addition, when I try to run PSIM 25.0, I receive the following license error:

Feature(s): PSIMPowerSupplyFeature
Error Code: 9
Error Description: Feature not found

Since my previous Student Edition license expired in June 2026, I believe I need to renew my Student Edition license through Altair One, but I cannot access the site.

Could you please check my Altair One account and Student Edition license entitlement, and help me restore access so that I can renew and use PSIM again?

Thank you.

Is there any way I can get a new license as if I renewed?

Thank you in advance.

I’d also like to know how I could recover my license key since my computer was stolen.

Hello Altair Support Team,

I am experiencing an issue where PSIM remains functionally restricted even though activation succeeds with my Student Edition key (LAH4R-T5HRK-XXXXX-XXXXX).

[Current Symptoms]

1. Activation: The activation process via Altair License Utility completes with "Activation Successful".
2. Behavior in PSIM:
   • PSIM launches without errors and can successfully open existing example files (.psimsch).
   • However, creating a new schematic (File -> New) is grayed out / disabled.
   • Most core features appear restricted, similar to a demo or unlicensed mode.

[Troubleshooting Attempted]

• Executed PSIM and License Utility with Administrator privileges.
• Set the system environment variable (ALTAIR_LICENSE_PATH).
• Completely cleared all local license caches (%APPDATA%, %LOCALAPPDATA%, ~/.altair_licensing, %ProgramData%\altair\licenses) before reactivating.
• Adjusted folder security permissions for full access.

Since I have completed all standard local troubleshooting steps and the issue persists, I am unsure whether this is caused by a backend token/profile configuration or something else entirely.

Could a support representative please help diagnose the exact cause and assist in resolving this issue? (I can provide my full License ID, Activation Key, and Host MAC Address via private message or email if needed.)

Thank you for your help.

Hi all,

Our company's Altair licenses (HyperWorks suite) expired last night, and we're completely blocked from working. I've been trying to reach support for over a week with no luck:

• Our regular contact's email is unreachable (mailbox full)
• Calls to that contact go unanswered
• The German support line isn't picking up either
• Altair One portal/helpdesk isn't giving me a way through either

I suspect this may be related to the Siemens integration causing some disruption on the support side, but I really need to get this resolved quickly since our whole team is locked out.

Has anyone else run into this recently? Specifically:

• Is there a different support channel or queue I should be using post-Siemens-acquisition?
• Any advice on how to escalate a license renewal issue when the usual contacts aren't responding?
• Is there a way to flag this as urgent within Altair One so it doesn't sit in a general queue?

Any pointers — including alternate contacts, a working phone line, or how others have gotten through — would be hugely appreciated. Happy to provide more account details via DM if that helps someone point me in the right direction.

Thanks in Advance

Kornél

I would like to:

1. Remove myself as the current Account Owner.
2. Assign another existing user as the new Account Owner.
3. Remove my access after the ownership transfer is complete.

Could you please provide the steps required to transfer the Account Owner role, or let me know if this change must be completed by Altair Support?

Hello Altair Support Team,

I am using the PSIM Student Edition and I recently changed to another computer.

I am trying to activate my student license on my new computer, but I receive the following error message:

“This license was already activated using different HostIDs.”

My student license is currently still activated on my previous computer. I would like to request that the previous activation/HostID be deactivated or reset so that I can activate the same student license on my new computer.

I understand that the Student Edition license can only be used on one device at a time. I am simply transferring my license from my previous computer to my new computer.

Could you please deactivate the previous HostID activation from your side so I can reactivate the license on my new computer using the same activation key?

I can provide my Activation Key and any additional information you require privately.

Thank you for your assistance.

Best regards,
Faruk
