Arduino IDE 18 and XP Problems

Just downloaded Arduino 18. Loaded drivers and moved Arduino to c drive program files. Went to open and was told to update Java. Updated to version Double clicked on Arduino icon to open and had the initial screen come up and then nothing. Did some research and decided to open using run.bat. Can't seem to find this file anywhere. Any help would be appreciated.

About 4 hours after this post I doulble clicked on the Arduino icon and it started. Shut my computer down, restarted and it still worked. Don't know what was going on there, but it seems to work now.
