I downloaded the trial of IDEA 4.5.4 for Win32 and the installation went smoothly. However, when trying to run the app (WinXP SP2) I was immedately greeted by a "Fatal Applicaton Error" dialogue with the supplemental text "the invocation of this application has caused an invocationTargetException". This is the error listing:
The result is the same using JRE 1.4.2.02 and 1.5.0.03, including numerous restarts.
I'm a bit dismayed by this since from all I've seen so far I'd really prefer IDEA over NetBeans and Eclipse.
