I've downloaded those 14 part files too, same result even with running it using /NCRC option, looks like the 181MB setup.exe is corrupted.
There is another Artcam 2010 with 9 part files, if someone had tried it then please share the result.
Ichan, Don waste time downloading the 9 Part version. Same problem with that too. Hope someone comes up with a working version. hmmm
