Oracle Sql developer error: could not install some modules

Question

I have downloaded a fresh copy of sqldeveloper (sqldeveloper-4.1.3.20.78-no-jre) from the Oracle website. When I unzip it and lauch the GUI, I keep getting the following error message:

Warning - could not install some modules: Dynamic Module Config - No module providing the capability org.netbeans.Netbinox could be found.

My system:

• Windows 7 32 bit Hp Probook.
• Jdk 1.6 , 1.7, 1.8 available in java/jdk subdirectory.
• Netbeans 8.0.2 installed

Answer 1

Finally got the way out after some dirty hours. Initially I extracted the sqldeveloper zip in a nested directory.

i.e: E://A/B/C/sqldeveloper.
starting sqldeveloper gui from the above directory threw erros.

Solution:

• Go in C:\users**UserName**\AppData\Roaming : delete SQL Developer and sqldeveloper folders

• Extract the Sql Developer zip in a new non nested directory. i.e: E://

• Start it and should work now

Answer 2

In my case it was enough to change JDK pass to Java 8 in the C:\Users\YourName\AppData\Roaming\sqldeveloper\19.2.1\product.conf file: SetJavaHome C:\Program Files\Java\jdk1.8.0_202

I have Java 13 as default and although SQL developer complained at startup it worked OK with it until I started it and went away from the computer, so I missed the warning screen. After that it started to show the "could not install the modules" error.
