Cannot install any ui's

[zareth]

I don't know what is causing this, but no matter what UI I try to use, I cannot get it installed. About halfway through the extraction process I get a message saying "Windows explorer has stopped responding". It all shuts down and i can't finish the installation of the UI. I have used UI's in the past with no problem. I have tried several different UIs and the same thing happens every time. Does anyone have any suggestions?
