I installed sql developer a couple of days ago and now I can't run it. When I click on sqldeveloper.exe, it start loading and then stopped. How do I fix this please?
When you post provide the FULL version you are using.
Could you run it 'a couple of days ago'?
If so, and you can't run it now then something has changed. What changed?
A common problem with the 4+ versions is using a version of Java SDK that is too old.
