is that the entire error? please copy everything you see in the View > Log panel, and let us know the versions of SQLDev, the JDK, and the OS you are running.
Hello yes thats the whole error, then the client crashes.
Nothing is written to the log.
sqldev ver. 126.96.36.199 - MAIN 16.84
OS windows 7
Searching the web for "loadlibrary failed with error 126 java" seems to point to issues with OpenGL and certain video drivers and/or environments with multiple monitors. Here are several discussions...
So it seems this issue is not specific to SQL Developer. The last discussion includes a video link in its last post saying that ".dll" is searched for rather than "atioglxx.dll" on 32-bit systems or "atio6axx.dll" on 64-bit system (in the C:\Windows\system32 folder), so a workaround is to copy one of those to ".dll".
You are correct, i run 4 monitors on 2 gfx cards. problem stopped occuring when i upgraded to latest drivers
