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.
There might be issue with JDK.
Get proper JDK location
File \sqldeveloper\bin\sqldeveloper.conf has the JDK location
SetJavaHome C:\Program Files\Java\jdk1.6.0_05
Set this to where the JDK files are located with the correct version that is installed
Try sql developer
