auto-updater not working on windows ia32

[vicentedealencar]

Hi, I am able to generate and host a win 64 release, but it looks like many users use Windows 32. I tryed to setup the auto-updater for that, but now there is an Exception that says There should be at least one full release, even though there is a full release there.

On a last try I removed -ia32 from the nupkgs and to the RELEASEs files accordingly, and it works. It is not ideal to but I will do this manually for the next releases.

See #359 (comment)

For windows consider only distributing 64-bit versions.
