I am trying to run my own legal copy of Propellerhead (http://www.propellerheads.se/) Reason 2.5 through Wine on latest Ubuntu on Asus (http://www.asus.com/) netbook, which has no optical drive. When the application starts, it asks me to ?Please insert the CD?, which I thought I knew how to do because after all, I had to mount the one of the three ISOs to start the installation. I run this Code: wine Reason.exe , and get this (output of wine Rebirth.exe &> /tmp/log.txt 2>&1.) Code: fixme:ntdll:server_ioctl_file Unsupported ioctl 24000 (device=2 access=1 func=0 method=0) This code repeats itself once a second while the GUI of the application Reason prompts me for ?Please insert the CD <cd name>, Waiting for CD...?. There is only a button for ?Quit?. This is the normal behavior, just like how Windows does it. In fact, after this CD load, it will request I load another CD before it lets me enter serial number This is how I mount the CD prior to executing the command line wine Reason.exe. Code: netbook@netbook-901:~/.wine/dosdevices$ ls c: e: e:: f: h: z: netbook@netbook-901:~/.wine/dosdevices$ unlink e: netbook@netbook-901:~/.wine/dosdevices$ unlink e:: netbook@netbook-901:~/.wine/dosdevices$ ls c: f: h: z: netbook@netbook-901:~$ cd ReBirth/ netbook@netbook-901:~/ReBirth$ ls demos Propellerhead Reason2.5_Disc1.iso Reason2.5_Disc2Orkester.iso netbook#1.rbs Reason2.5_Disc3Sound_Bank.iso netbook #2.rbs Reason Installation wine errors.txt mountng.txt rebirth_iso_installation.iso netbook@netbook-901:~/ReBirth$ sudo mount -o loop Reason2.5_Disc2Orkester.iso /mnt/reason2 netbook@netbook-901:~/.wine/dosdevices$ ln -s /mnt/reason2 e: netbook@netbook-901:~/.wine/dosdevices$ ln -s ~/ReBirth/Reason2.5_Disc2Orkester.iso e:: netbook@netbook-901:~/.wine/dosdevices$ ls c: e: e:: f: h: z: Rebirth 2.5 is not in the AppDB (http://appdb.winehq.org/objectManager.php?sClass=application&iId=811), but the subsequent versions are (i.e. 3.x, 4.0,5.0). I?d like to run 2.5 because that is the version I own and run on my Windows Digital Audio Workstation counterpart. I?m running wine version 1.2.3 I do not understand the switches of the link and mount commands very well, nor do I understand how wine ?sees? the virtual CD-ROM drive. I am adapting instructions from this page (http://createdigitalmusic.com/2010/10/how-to-install-rebirth-in-linux-get-a-free-rack-of-beat-machines/), which I successfully completed to run ReBirth (http://www.rebirthmuseum.com/), Reason?s predecessor. I believe this will work. Could someone just help me mount the ISO CD correctly? I also will need to know how to put in a 'second CD' while "ingame". I assume I could just create two virtual CD-ROM drives and am willing to do that. I recreated the ISOs from the original CDs again when all of this failed the first time, but that did not help. The same CDs works in Windows. I even copied the entire subdirectory from "Program Files" and dropped into the corresponding wine folder thinking these files were 'activated', and I get the same as stated above. Thank you for your time.
