Openrefine: Problems starting OpenRefine

Created on 20 Feb 2020 · 2Comments · Source: OpenRefine/OpenRefine

Describe the bug
I cannot launch OpenRefine and work with any projects.

Current Results
When I run openrefine.exe, the cmd window opens, pauses, then displays an error message. I have tried deleting it and redownloading it, checking my Java version with the IT department, and checking the JRE/JDK version.

Here is the error message:

It looks like you are running OpenRefine from a network location - I have seen issues with this before although not been able to work out what the underlying problem is. Are you able to download to a location local to the computer you are using?
