I have a excel spreadsheet that I would like to write a value to pi. After changing out computer and re-installing pi datalink having issue with running vba code to write the value into pi using piputval. Macro is returning Pibufss service is not running. Unable to buffer. PI buffer subsystem should be running but isn't. Start attempt failed. Pibufss is set to manual and is stopped. I cannot start it with current configuration (No Authority to Local System). My question is does the PiBufss need to be started. Would this be a reason for values not writing to the pi server.
