Driver problem between DSO nano and Windows7/64

After installing DfuSe_Demo_3.0 and connecting my DSO nano to the PC
Windows7/64 searches for the driver but cannot find it.

What did i wrong?

(Current DSO Nano firmware is V1.520 and i liked to upgrade it to V2.4)


In addition:

In Windows7/64 / manager / usb-controller the DSO Nano appears as unknown device
(Code 43).

The Dso nano is installed with the dfu’Se Demo V23.01 Setup_x64



DfuSe V3.01 Setup x64


Problem solved.

For driver installation the starting sequence of the dso nano is to hold the M- Button when starting.
The rest is as described.
