I've downloaded the SQL DEVELOPER v188.8.131.52.48-x64.zip file three times now.
Each time i create a new folder in c:\ and unzip the file to create the c:\sqldeveloper folder.
From here I simply click on the SQLDEVELOPER.EXE file.
The result is a weird yellow background window with a menu consisting of 'GoTo, Tools, View, and Window'.
None of the menu items go anywhere or have an ABOUT menu which tells me what it is.
Meanwhile the LOAD bar is about 10% of the way across the screen and hangs there.
I installed jdk-7u51-windows-x64.exe earlier this morning.
My Sql Developer v3.2 continues to work just fine (thankfully).
Anyone have any suggestions ????
