I'm sorry, but this method is confirmed to work on all the supported OS, which do not include Windows 7 beta versions.
We have confirmation by many users that the with Windows 7 final, the program works, but we can't guaranteed anything, unless you see it under the system requirements on the web page, that clearly mentions only XP and Vista, which are the only ones we officially support.
If you really wanted to use it on an unsupported, and not even in final version OS, you should have taken advantage of the freely downloadable Trial version, which is extensively advertized all across our website.
