[BUG] QR code generation fails on Windows Server 2025 because wmic is not available (WMIC deprecated)

[ashishsabu]

Hi Team,

While testing multiOTP Credential Provider v5.10.1.2 on Windows Server 2025 Standard, an error is encountered during the QR code generation process. Since WMIC is officially deprecated and no longer available on recent Windows versions (Windows Server 2025/Windows 11), it appears the QR code generation step may still depend on wmic.

Commands executed:
multiotp.exe -fastcreatenopin testuser
multiotp.exe -qrcode testuser testuser.png

Error: 'wmic' is not recognized as an internal or external command, operable program or batch file.
PHP Warning: Undefined array key 0 in C:\Program Files\multiOTP\php\multiotp.windows.php on line 1526

Error screenshot attached for more details:

Could the team please confirm whether multiOTP has been updated to operate without WMIC ? If not, is a fix or workaround planned for environments where WMIC is unavailable? Also, is the impact limited to QR code generation, or could other functions be affected?

Thank you.

Regards,
Ashish

Hello @ashishsabu,
Yes, you are right, as WMIC is now deprecated for Windows 2025, our code evolution no longer use wmic on Windows plateform.
The next version of the sources of the project will be available soon, both for multiOTP and multOTPCredentialProvider.
Regards,
