Besides you can copy the pspp directory from your old computer to your new computer. At that moment you only miss the file associations and the entry's in your start menu. Both can easily be created manually.
However as Alan already stated, I can't think of any reason why anybody would chose that pre-historic version above the current version.
Have fun

I didn't see those. I'm not sure those are "releases" and these tarballs
need to be compiled, which is far beyond the capabilities of most
Windows users.
Harry Thijssen has put a lot of effort into creating cross-compiled
binaries for Windows and until someone creates a native Windows port,
Windows users should stick to the binaries that Harry provides at
http://pspp.awardspace.com or on sourceforge.
Xavier's best bet is to find an old copy of one of Harry's 2011 binaries
of 0.7.8 somewhere on the net. Opensource means no one is going to stop
a user from using an ancient version of PSPP (whereas, try buying a 2011
copy of SPSS), but the reality is that software "ages" and that's a good
reason to try to use the latest versions.
