Thanks, now I can see that IE10 is not supported for Oracle.
I´ve downgraded IExplorer and now I have IE9 with Java 6 (25) both 32 bits.
I can open the applet and get access to my Oracle Forms app, but through LR, the applet still not loading.
Seems to be a problem with java... How could I be sure that during recording I´m using 32 bit JRE 6?. In Java console I only have installed Java 6 version 25 - (32 bits)...
