Comment 1 for bug 1456183

with respect to the eps import, you can do the following: first of all confirm that your path variable contains the entry:
C:\Program Files\gs\gs9.00\lib\
or something equivalent to it, depending on which version you installed. This will allow Inkscape to find the batch files called ps2pdf, etc. Secondly, Inkscape needs to be able to automatically find the file gswin32c.exe. There are two ways to achieve this. One way is to copy the file gswin32c.exe from the directory C:\Program Files\gs\gs9.00\bin to the edirectory C:\Program Files\gs\gs9.00\lib. The second way is to put the directory C:\Program Files\gs\gs9.00\bin\ into the PATH variable. Personally I prefer copying the file, but either way should work.
