In the past year, I have used the Sensor AFE Software for SPIO-4 board and LMP91000EVM on several Windows 7 and Windows 10 computers. I know there is a problem with the LMP91000EVM software in 64-bit operating systems, but the "Enable Unsigned Drivers" solution has been very successful.
In the last use, the software prompted me to check for updates. I chose "Yes" and then the software could no longer connect to the SPIO-4 board . Device manager of the computer shows "Device is not installed correctly" . Moreover, the driver cannot be reinstalled correctly, even on Windows XP.
