Don't call GetFileVersionInfo(), which calls LoadLibrary() to be able to access the module's resources. Loading modules from the crashy process into the handler process can cause trouble. The Crashpad handler definitely doesn't want to run arbitrary modules' module initializer code. Since the VS_FIXEDFILEINFO needed is already in memory in the remote process' address space, just access it from there.
