IE 6 standalone png transparency support

I am adding png with transparency to a web site. I need to check how this will work with IE6, and have installed the IE6 standalone from evolt.

However when I visit sites using the various png display hacks/workarounds for IE 6, I do not get the transparent png.

I am guessing that the standalone version of IE6 that I downloaded (which may be the original IE 6) did not come with the png transparency filter capability. There apparently is a IE6 fp1, and perhaps this has the filter.

Is this a known issue with the IE6 standalone?
