Hello my friends !!
I'm very new at almost everything about Arduino but I had the same problem which now seems to have solved. I did what Louis said in addition to what I inadvertently did afterwards!! I just copied the folder containing the arduino 1.0 stuff (which was originally on my desktop for some reason) and pasted it in my programfiles folder(and not even in the programfiles x86 !! ) and then I ran it from that location and it miraculously came up !!! I'm not even sure whether it's gonna work on your device or weather it can be a long term solution but I hope It can help you figure out the root of the problem. Good luck XD
