[ BUILD # : 200505031930 ] [ JDK VERSION : 1.5.0_02 ] When installing NB4.1 the registry elements to match file type (.java) to the app and app icons are not getting set. Every .java file should be showning the Netbeans icon and double-clicking should open the app. This looks to be fairly recent (since beta), previous versions of NB (3.6, 4.0) did not have this problem. Not certain that RC1 or RC2 properly set this but I think that the March/April dailies did.
.java file association with IDE is not set by installer. NB 3.6 installer did it. But from NB 4.0 it was removed. You can set file type association manually: You must use command <PATH>\netbeans.exe --open "%1" for java file type (file with java extension). *** This issue has been marked as a duplicate of 47629 ***
