I opted to purchase the download version of Premiere Pro CS3.
When I login to my account on the Adobe Site, I am given the option to download the software, which requires an ActiveX downloader control to be installed and used.
The ActiveX control works (Vista) in itself because I am able to use it to download trial software.
Hoever, for my purchased software, the download link just keeps going in a circle, asking me to login to my account the moment there's any danger of the the thing actually being downloaded.
This appears to be a Vista issue, as I was able to get the download on another PC (XP). This was a pain in the neck, however, as I did it via Remote Desktop and it took an age to get my purchased software.
I did all the usual stuff about enabling cookies and followed the ActiveX browser configuration instructions faithfully, without success.
No, I don't have Java. According to the Adobe notes it's not necessary to have Java for the combination of Vista + IE7. The Akamai downloader (ActiveX control) does work when downloading trial software. It's only when trying to download purchased software that the download site goes into a loop and asks me repeatedly to login to get my software. Oh, and if you go to the page in the FAQ that tells you how to uninstall the Akamai software, you just get a message saying you're not authorised to view that page! Sweet.
