I normally just download the zip...will this still work?

I just bought it and it downloaded the zip and added it. It seems like I need to use the .exe you have for updating the addon. Is that correct?

I don't want to use that, I prefer to download the zip and manually install it.

Apparently you need the Zygor client to download the historical action data for your server.
I did not try the gold guide yet and cannot say how much it would affect running the gold guide without this data.
But making these data available for manual download would be difficult as there are many servers so a list would be rather large and a complete data file would also be a large download, the files I have are between 295 KB and 345 KB.
