OneAPI 2025.1.1.34 + A certificate chain could not be built to a trusted root authority

[Doug_2025]

We are working on a project to install the above mentioned version of OneAPI and keep running into the same error. "A certificate chain could not be built to a trusted root authority."

This is a new install and Visual Studio 2022 17.10 is successfully installed offline, as the target computers for this installation are all air gapped. And yes the Desktop development with C++ was installed without any errors. 

When attempting to do the OneAPI offline install it keeps failing with the cert authority message above, and we utilize the command intel-oneapi-base-toolkit-2025.1.1.34_offline.exe -a --silent --eula accept but again it fails with the cert message? 

In previous attempts I did install a new cert chain from the internal CA authority, but it still fails. 

We are installing on windows 10 21h2. 

Visual studio was installed successfully and the system rebooted, but we can not get OneAPI to install. 

I have searched the community and found other posts, but none of them listed any kind of resolution or fix. 

Any ideas/help would be appreciated. 

Thanks,

Doug

Haarika,

Thank you for the response. We have multiple air-gapped environments that we will be needing to deploy this into. The environments are only accessible from within the workspace where the systems are located, again they have no internet access from these environments. 

We are not running any scripts and to perform the installed we are utilizing the installation instructions that were provided by Deeksha in a previous communication. 

I have attached the full set of logs and compressed them. 

Let me know if you have any problems opening it. 

Thanks,

Doug

Hello Doug,

The error "A certificate chain could not be built to a trusted root authority." is now resolved after sharing the correct set of certificates offline with you. We will continue to investigate the original installation issue.

I would like to request you to create a new thread for any further queries you many have or any new issues you run into.

Thanks
