When you go to Adobe's website, do you get the "successful" thing, but then it doesn't work?
I've found that keeping that window open while I load the new page in a different window worked sometimes. It seems kind of hit or miss with IE, so I'm not sure what works and what doesn't.
Eventually I got tired of messing with it and just downloaded Firefox and haven't had any problems since.
I have tried that and it does not work for me LOL thanks much. I have followed all the recommended help files and it just won't install properly. Dagnabit
