Hi,

I recently and suddenly encounter an error message "Could not find or load main class XXXX\AppData\Local\Temp\elasticsearch" when I tried to start an Elasticsearch instance. My username contains whitespace. It seems like the Elasticsearch only obtains a partial path correctly (i.e., Jims John --\> John). This issue occurs after the most recent windows update.

Any solutions?

Thanks,

---
