Description: Does not install
Details:

Downloaded the zipped up package for Win 32. Started the installation with
the .msi file. After asking me what language to use (I chose English), I
got a message that the .msi file was invalid, and the installation simply
failed. I downloaded it via FTP from one of your mirrors. Not a very
promising start...
