[Inkscape-user] Can't start on Win7

I was using an older version of Inkscape (not sure which one), and couldn't start it: "The application was unable to start correctly (0xc0000005)."

I upgraded to latest version (0.48.0) after an uninstall. I deleted all user preferences too. I am getting the same error.

I checked in my AppData/Roaming/inkscape, and all I have in there are empty folders.

What do I need to do to get this working?
