Downloaded the ExternalEditor.nbm file. Installed this manually using the update centre wizard. The (after some hunting -- it's not documented) launched tools setup wizard to set the editor. I restarted the system and tried to edit a file. The GUI stuff works, but the text bit failed. The text in the log file will be included (I hope I can add this at the next screen).
Created attachment 11038 [details] IDE log file -- as requested
I'm not sure what you mean by "the GUI stuff works, but the text bit failed.". Did gvim start? The ide.log file shows exceptions during startup, but that can either mean gvim didn't start or it can mean it started but netbeans couldn't connect to it. What version of gvim are you running and does it have the netbeans support enabled? You can get this info inside of gvim (or vim) by typeing ":vers". The first line contains the version number and you can tell if netbeans is supported by looking for "+netbeans_intg" (its there) or "-netbeans_intg" (its not there). You may need to change the default options for the externaleditor which are really set up for Unix and X11. The only one absolutely necessary is the "-nb:localhost:3219:changeme" option. The rest do things like set up fonts and colors, but do this in a non-Windows way. Hopefully they're just ignored on windows but I don't know this for sure as I don't run on a windows box.
