ESP32 not detected by Windows 7

[vibram]

Hello

I use an esp32 dev kit (WROOM 32U)
I program it with Arduino IDE and use the BluetoothSerial library
The device is working well when I pair it with an android Phone and my professional laptop on windows 10 but impossible to detect the device with my Windows 7 Computer. The ESP is not visible at all, nowhere
The computer doesn't have bluetooth initially so I'm using a BT5.0 dongle bought on amazon.

Is there a way to patch this?

Thank you for your help
