Yeah, I'm on Windows XP SP3. IIRC, the installer spends such a long time "checking space requirements" because it has to compare some checksum of the files to be copied against the versions already present, which are, unusually, not stored inside the files for Calibre due to the fact that it's written in Python. So my guess would be that it recognizes which files to copy because it looks at each file anyway. I don't know how the use of ZIP files changes this assumption, though.
