Thanks for the reply. I was not trying to use the actual UNC paths. I was trying things like this: wine "/mnt/apropos/Winstall/Winstl32.exe" "/mnt/apropos/Winstall/apr6x_LocalLinkClients.lst" "/NoNetwork" In case others make this newb mistake: I mapped "/mnt/apropos" to "D:" in winecfg per your suggestion and ran this: wine "D:\Winstall\Winstl32.exe" "D:\Winstall\apr6x_LocalLinkClients.lst" "/NoNetwork" which worked! It installed and placed a shortcut on the desktop. Now it looks like the program launcher isn't cooperating: http://forum.winehq.org/viewtopic.php?p=22960#22960
