Comment 1 for bug 1715339

We recently had a few issues that were caused by old files remaining from a previous installation.

Could you therefore check if the issue can be solved by:
- completely uninstalling Inkscape
- deleting the program folder
  ("C:\Program Files (x86)" or "C:\Program Files" respectively)
- installing Inkscape again

Alternatively you could check if Inkscape works if you download the .7z archive, extract it into an empty folder and run from there.
