If you are trying to install Oracle client onto a Microsoft Vista computer, there is a possibility after executing the setup program and waiting for a few seconds you will get a pop-up window stating that oui.exe has stopped working. After a few more seconds of ‘trying’ to figure out what’s wrong, it stops — leaving you to click ok and wonder what happened.
Well, I ran across a random message (thanks oracle forum user user599812) that suggested that if you move your oracle setup folder closer to the root C:\ folder, you might solve your problem. I am here to say that we had this problem, and moving the folder to C:\ solved the problem.
