Installed Inkscape via the portable-apps platform 17.1.1.
After the installer was done, I tried to run Inkscape from portableapps menu. However the window never came up.
Workaround: Downloaded the 7z archive from Inkscape home page, unpacked it and was able to use. However - it doesn't show in the portableapps menu that way.
