Hi, you need to place the 5 bin.files and the GWX exe into one folder then click the GWX exe .. this will install GWX. Once installed, download GWX 1.03 then click on it, follow the prompts and you will end up with GWX version 1.03. The reason GWX is stating you haven't the key components is presumably because you are lacking some or all of the bin. files.
If you encounter any problems then don't be afraid to post, there are plenty of people willing to help you on this Forum.
