Fences 0.99 installer wants .NET 2.0

Please see the image at right. I am running Vista 64-bit SP1. I presumably already have .NET 3.5. I tried to install 2.0 just in case, but ran into problems. First the link in the dialog is for 32-bit OSes. Second, the 64-bit .NET 2.0 SP1 version out there doesn't install on Vista.
Since the next button was enabled, I thought I could attempt to ignore the issue, but no dice. The button does nothing.
