I just tried the download from a couple of different sites and received various error messages, including the connection timed out, source not found, etc. I then went to sourceforge (where the download's actually coming from) and found success using the Gimp page. According to that page, version 2.6.1 is for Windows 9x and version 2.8.9 for Windows 2000/XP, with 2.6.8 being no longer available. Thus, you'll have to use the newer or older version, depending on your operating system.
Hope this helps,
Can someone tell me why i can not download GTK+ Runtime Environment 2.6.8 from CNET or any other site? The message is: it is impossible to establish a connection Thanks.
