Hi
The forum is correct you have not got a supported environment if you have greater than 10.3. However if it runs at the moment have you tried downloading the individual patches from the website and install it as a standalone? These all require the incrementals to be installed.
Here is the link:
http://www.adobe.com/support/downloads/product.jsp?product=1&platform=MacintoshIf this still hangs but you have 7.05 working then simple deactivate the download updates check. Select Edit|preferences => Updates and select 'Do not check for updates'.
