wine users - Jul 2011 - Second CD not mounting

I've asked for help on the ubuntu forums over this matter and no-one
responded so I've decided to get help from the main developers, I've
been trying to install several softwares under wine but noticed that the
software isn't happy with two disks or more, every time when I try to
install a software under wine and asks for the second cd I insert it but then it
doesn't load (i.e mount) but every time when I decide to stop the
installation it then detects the second cd and loads up which is too late. Is
this bug happening to me only or is it happening to other people as well. It is
alright with a single cdrom disk but not with two disks or more.

I know it seems counterintuitive, but, instead of cancelling the installation,
just tell the installer to continue.

I had the same thing happen to me recently under Linux Mint Debian. When I
noticed that Nautilus only saw the change in CD when I stopped the Wine
installation, I realized that the CD was indeed being "mounted"
(recognized as inserted), but that Nautilus/D-bus simply was unable to inform me
of that (presumably because it was blocked by the Wine process; some versions of
InstallShield are very aggressive about blocking "other" bus
communications). I realized that I didn't in fact care whether Nautilus
could see the CD, but only that Wine could, so I took a chance that Wine already
did, and continued the install.

Sure enough, the installer read the files it needed off the newly-inserted
second CD and install completed normally.

If that leap of faith doesn't work (it really should, under those
circumstances), you can always make an ISO of CD2 (using your CD burning
program, or just using dd in the terminal), create a mount point for it, mount
the ISO to that mount point, and link that mount point as a second,
"fake" CD-ROM drive in winecfg. When the installer asks for the second
CD-ROM, send it to that drive letter and it should read the mounted ISO as CD2.

Hope this helps.

Does "wine eject" in a terminal not work?
