I just downloaded GH and the file downloads as a zip file which you can open but then nothing in the zip file shows an install file to click on, which might lead one to think that they have to install the files manually. What a drag that would be.
I don’t know how many people know they have to change the extension to .rhi and not zip, I read it’s windows that is doing this by searching this site but the fact that McNeel doesn’t warn you of this anywhere is another place where the ball is dropped. When one downloads the page should say warning extension on file might download as a zip file if this happens change extension manually to .rhi
Please post a fix for this and let the community at large know that this might happen not just show the fix in one tiny thread accessible only on this list, better would be to figure out how to get your extension of rhi to be noticed by windows so that it actually works without user intervention.
