It would be great if the download installer link was different for each version.
As is, I just tried to download v29 and got v30 instead because you replacedhttp://www.srware.net/downloads/srware_iron.exe
with the latest version.
Unlike google chrome, you do not include an auto updater, this is good because sometimes you don't want to update due to some issue in the latest version. But finding and downloading an older iron version is a real problem since you delete them from the server and replace them with the latest version.
So please, make the link be to a file called srware_iron_30.0.1650.0.exe which will remain available even after v31 is released.
