                    from iso
           Product: Wine
           Version: 1.2-rc2
          Platform: x86
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: kernel32

        ReportedBy: [e-mail]

(This reminds me of bug 22428.)

says you need -o uid=XXX,unhide.   You can install from an .iso 
mounted with that (and ro,loop), but you can't start the game, it says
please insert disc.  Pointing d: and d:: at a real mounted disc works past it.
A +relay,+file log says

0009:Call KERNEL32.GetVolumeInformationA(02f9d290
"I:\",02f9cce0,00000400,02f9d22c,02f9d230,02f9d228,02f9cae0,00000200)

0009:Ret  KERNEL32.GetVolumeInformationA() retval=00000001 ret=023aaed3

It then does

0009:Call KERNEL32.QueryDosDeviceA(02f9cce0 "I:",02f9cae0,00000200)
ret=023ab4b1
0009:Ret  KERNEL32.QueryDosDeviceA() retval=00000019 ret=023ab4b1

trace:file:CreateFileW returning 0xffffffff
0009:Ret  KERNEL32.CreateFileA() retval=ffffffff ret=0236c2b2

a bunch of times.  Looks like it's trying to access the 
iso but failing (do we not support \\.\HarddiskVolume2 for 
mounted isos?).
