Hi Stefan,

The Windows version (I've tried with 0.92 rev1 32 bits) of Inkscape will effectively import AI 8 files but we first have to install uniconvertor-1.1.5-win32 from the link you provided.
After installing, it is necessary to apply a patch to connect Uniconvertor to Inkscape.
The patch installation intructions will be in c:\ Program Files (x86)\sK1 Project\uniconvertor-1.1.5\docs\about-patch.html
After that, it will be possible to directly import (select Import - File Type : Adobe Ilustrator 8 and previous) to Inkscape without errors.

Thanks to Michael for remembering it and to Stefan for this link !
It saves from first opening in AI to convert it.

Michel
