VCI3 an VCI4 IXXAT Drivers for WIN11 - Installation issue due to security certificate expiration

Hi everyone, I'm experiencing an issue with the "vcilva.dll" and "vcilva2.dll" drivers installed by the LabVIEW add-on (both VCI3 and VCI4) on a Windows 11 system.

Unfortunately, the OS doesn't recognize them as safe drivers and marks them as untrusted due to an expired security certificate.

I forced the installation anyway, but Secure Boot blocks it, and WIN11 shows a blue screen as if the OS has been corrupted.

Is there an updated version of the LabVIEW drivers with a valid certificate that can pass Windows 11 security checks?

If not, how can I solve this problem?

Thanks in advance for any help!
