Thanks for the suggestion. But I put question in this forum only after doing the above basic steps u suggested. I didn't find anything for IE 5.5/IE6.0. So if you know exact url then please let me know.
Write to firstname.lastname@example.org, they are the right person to provide you authentic info regarding iMAC version. Although version for iMAC machine is deploymentwise not very popular but if you write then you will get.
Carnifex is quite reasonable, Mac indeed is an outdated configuration. But still if you write to email@example.com your luck might help you as at times they might fetch old stuffs too for distribution. I suggest you write mail and see if you receive answers from them. Otherwise Bryan too is quite reasobnable, keep accessing this bulletin board.
For future try to move on from Mac to latest and popular configurations, maintenance wise that would be better option.
Sandy is looking for a higher version, not an older one. I didn't notice that the link to the MS site was for 5.2.3 and 5.1.7 depending on the OS you run. I would assume that that's the latest version for Mac.
