I have downloaded the current Alfresco-Community-3.2-Full-Setup.exe
When I try to run it, I get an error dialog explaining that twapicallback.dll cannot be found. I have downloaded the file twice and am now downloading an older version from SourceForge that is dated Jul 3, 09 to see if that resolves the issue.
I am not sure if perhaps it is something that I have missed or if it is maybe something that didn't get included in the installer bundle.
