I couldn't resist and tried it. Unfortunately, it reports that the installation is finished and starts a black dosbox. Than the system crashes and reports a problem with gdk-pixbuf-query-loaders.exe
When the error messages and the dosbox is closed, a nice finished screen of the installer pops up. Does the installer try to start psppire?
When I start the installed pspp from a dosbox I get: == pspp: cannot find output initialization file <use '-vv'to view search path> pspp: error reading device definition file pspp: using default output output driver configuration
== and then the PSPP prompt.
Psppire started from a dosbox gives a crash on psppire.
