can get arduino.exe to work in vista

hi i have windows vista ultimate 32 bit and i recently installed arduino-0015 on my computer and when i click on arduino.exe i get the error that says error getting the arduino data folder. I have tried runnings as admin and tried run in windows xp compadability mode. I noticed another post and the solution was to change something in the properties.txt file but i dont have that file. I have also tried installing other versions but nothing has worked. Any one have any ideas? Thanks for the help

if anyone else has this problem the post i read didnt say the the preferences.txt file was in the lib folder. so found the file and changes it and works great.

What folder did you install it in (I'm assuming you just unzipped it somewhere)
