Q:

Oracle Sql developer error: could not install some modules

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

A:

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
