Beginning with xlsgen 3.5, the main setup is split into smaller coherent pieces.
The first split is between 32-bit and 64-bit. One setup is 6 MB in size and installs the 32-bit version of xlsgen, which means the 32-bit dll and .exe built on top of it, as well as sample code. This setup is marked 3.5.0.x (32-bit).
Another setup is also 6 MB in size and installs the 64-bit version of xlsgen as well as sample code. This setup is marked 3.5.0.x (64-bit).
Another split is about the documentation. The documentation is actually online as well as offline so there is no reason to download the offline documentation every time we ship an update. The documentation is now separate as a 5 MB file, xlsgen.chm, available for download on our website.
