I wonder why the ST25PC-NFC program closed after run in my new computer with Windows 10.

Actually, I download ST25PC-NFC program on web and installed in a new Windows 10 to my computer. Unfortunately, the program cannot run properly. The program front page would pop out to screen and closed the window immediately.

Hello and sorry for the inconvenience. The program is designed to run on Windows 10 so this is not normal behavior.

Do you mind answering a few questions please :

What version did you download?

Have you restarted the computer after the installation?

Do you have a reader connected on the USB port, and if so which one?

Thank you!

What version did you download? Windows 10 (21H1)

Have you restarted the computer after the installation? restarted many times

Do you have a reader connected on the USB port, and if so which one? yes we did connect the ST25R3911B-DISCO

[KYip.1]

any driver need to installed to Windows 10 (21H1)?

please advise.

Thanks for the answers. I'll assume you downloaded and installed v2.5.0 of the ST25NFC PC software.

Have you tried running it in Administrator mode ?

In case extra drivers were needed for Windows 10, I suggest that you install the 3911B-Disco PC GUI software.

and see if the ST25R3911B-disco board is recognized.

Then try the ST25PC-NFC again.

actually, the 3911B-Disco PC GUI software can run in our computer very well.

However, my computer could not run ST25PC-NFC program properly, it is our concerns.

It is because our original testers build with ST25PC-NFC program, if I make it change to another program, I need to modify our test procedure and inform 5 different location factories, US, Mexico and China.

That's why I'd like to insist to make things happen with ST25PC-NFC with my computer in Windows 10 (21H1).

What happens when you run the ST25NFC-PC software in Administrator mode ?

Also, could you please try and launch the Windows EventViewer to see if you get any clue on what could cause the problem?

Hi Damien,

Thanks for your support.

I will try it again and see any error coming out in Event Viewer.

I will get back to you once I resume the computer in our factory production.

Thank you,

Hello Wai,

We have found a Windows 10 machine with the 21H1 update and the install works fine.

Can you tell me if the crash still happens for you when there is no ST25R3911B-Disco board connected at program start?

Thanks,

Damien

Hi Damien,

thanks for your updated.

actually, our factory removed my remote control access right due to hit our internal IT maintenance schedule.

I will try again and update you once our remote control ready.

Thank you for your continuous support.

Thank you very much.

Hello Wai,

we have investigated Windows 11 installation issues on our side and this may solve your problem:

1. Unzip the attached zip file
2. Copy the 2 files named msvcp120.dll and msvr120.dll into the app\ folder of the install directory of the ST25PC-NFC software. For example: "C:\Program Files (x86)\STMicroelectronics\ST25PC-NFC\app\"

Launch the application again.

Regards,

Damien
