Hello,

It seems to be a certificate issue. When I tried re-installing this same tool on my Windows 11 PC, I get a message regarding the certificate of those drivers:

I manually clicked "Install this driver anyway" (it came up about two times), and it eventually installed.

Did you see a similar dialog on your side?

I'll also reach out to the Tools team to get their insight (due to holidays, the response will likely come in mid Jan).

Thanks,
Toby

Hello,

An update, this was likely a temporary issue with certificate, can you re-try the install?

Thanks,
Toby

This is permanent issue. Problem is that TI CA certificate used for signing drivers' certs was expired. So, Windows disallow installation of such stuff, at all, if configured correctly.

To bypass this issue Windows OS must be reconfigured to ignore root cert issues. I did it and it helped. But it is a serious security hole and shouldn't be considered as valid solution. Please correct CA certificate, reissue drivers' certs and resign the drivers. Then all be flow smoothly for everybody

Please ping me when refreshed drivers are available.

Anyway, thank you for your assistance and support! 

Understood, and thanks for sharing your workaround.

Long term we are moving to SmartRF Studio 8 all the CC13xx/CC26xx devices.

In the meantime, our team has not observed any functional issues related to the drivers associated with SmartRF Studio 7. I will check if we are able to update the TI CA certificate.

I just re-tried the install (uninstall + install), and I do not see the same prompt as reported previously.

Can you try an uninstall + install without the "Windows OS must be reconfigured to ignore root cert issues"?

Hello Toby,

I'm fully immersed in the current development process and don't want to change the working environment right now, sorry about that.

But I'll definitely check the certificates/drivers again once I get a new Windows laptop, hopefully in February 2025.

Hello Toby,

Let me lit some light on the issue without re-configuring my environment.

1. Here is a way how to check driver's cert:

- select .INF file

- right click

- Open with... > Crypto Shell Extensions

- View Signature > View Certificate

Check Expiration dates of all certs in the chain!

2. Problem cannot disappear automatically or be temporary, if cert is expired, or any higher level cert is expired, then trust cannot be established.

In my example, with drivers I got from TI site or TI e2e forum, drivers were signed with TI cert expired in 2020, even CA cert expired in 2023...

Please confirm you can follow and repeat these steps with similar results.

3. Depending on Windows config, OS may discard any attempts to install drivers signed by expired CA certs without offering an option to continue (like in your case). It may differ from the case when CA is unknown or untrusted but still not expired. Anyway, drivers must be signed by valid and not expired certs, this will present professional level of the publisher/manufacturer.

Please let me know if you need more clarification from my side.

Hello,

Thanks for the details.

I've passed along feedback to the team to evaluate next steps.

Thanks,
