can you please try to uninstall the QE version on your windows
partition and check against the binaries posted on the alternate
download site here:

http://rpm.lammps.org/qe4win/release/index.html

please also make certain, that you have only one version, serial or
parallel installed at the same time.

that is good for you, but i'd like to track down the origin of this,
i.e. whether there is an issue with the installer packages or the
binaries on qe-forge are mixed up. so in the interest of other QE
users on windows, please make the test i suggested.

thanks,
     axel.
