It is a uncommon issue, probably issue during the upgrade.

By the way, this error message is likely caused by invalid file name in c:\Program Files\Splunk\bin OR $SPLUNK_HOME\bin. Search for a file named program or files or Splunk or bin and likely 0 byte size. If you find it remove it and try to startup.

I had the same problem during a upgrade on windows.

I checked in the Splunk folders, and found a zero-byte file named Splunk. I renamed that to zzzSplunkzzz, tried to start the service, and it started fine.

thanks
