I tried to install Netbeans 5.0, Netbeans 5.0 + AS, Netbeans 5.5 preview. All failed (by just "going away") after I clicked Next on the wizard page verifying the location to install. Even getting and extracting the ZIP bundle didn't work: it started, showing "loading modules" and then went away. Various logs showed "nullPointerExceptions". My Windows XP user account folder name was "David Hunt". I solved this by creating a new user account named "David". Everything now installs and works fine. I suspect the space in my user account folder name is the culprit.
Please can you attach IDE log to see exceptions?
I just tried to create user account with space in name and both installer and IDE works fine. I suspect it is rather duplicate of issue #64380. To confirm that change your desktop theme to default theme. See issue #64380 for more details. If you attach IDE log file here I can see if it is the same issue or not. You can also get more detail output from installer using-is:extract command line option. It will extract setup.jar from installer exe file. Then run java -Dis.debug=1 -Dtemp.dir=<Path to any existing dir with r/w access> -jar setup.jar.
No response. *** This issue has been marked as a duplicate of 64380 ***
