1. The link for IE Full installer on this page is wrong:
It doesnt actually download an executable, but instead goes to the standard SW installation page.
2. The link under Netscape Full Installer does download a standalone installer. However, when I use that to install the full version of the SW player, it still requires a secondary installer when it encounters a SW file which was created by earlier versions of Macromedia Director (just as SLIM version does.) Shouldn't the Full version install everything SW player requires to play any SW file?
Not quite sure what you are asking; there is no separate installer for IE and other browsers; just the slim, the full, and the MSI.
I had troubles too, but solved it. Adobe has just put the wrong link, they put the slim version for both slim and full.
To get the full version:
Change the word "Slim" in the URL to "Full", but I'm still not sure if it is as I see no difference.
