I was able to get past this problem by:
* renaming the flash drive letter name to be the same as on the P4 machine
* installing the missing fonts on the AMD machine
* opening the SVG file by: right-click-> open with -> browse -> InkscapePortable.exe (v 0.47)
The file did not work correctly if I opened Inkscape first and then opened using other methods.
