i yust got *cough* Pirated*cough* bloodrayne 2, and i now have 4 CD files.
i got daemon tools and i tried to mount them, but i got 2 few devices for 4 cd's.
Alcohol 120 is used for burning CDs onto your Hard drive as images of CDs for use with Daemon. I have both, I know roughly how they work.
From your post it looks like you have the images for all four CDs but not enough virtual drives.
Right click on the Daemon tools icon in the bottom right hand side of the startbar, Hover over Virtual CD/DVD-ROM, then haver over Set number of devices, and choose 4. Then mount different images in each of the four virtual drives.
Or you could do what Dboy said, and just mount/unmount them.
Well, that could work... but if you still stuggle >>
Open Alcohol and select Image finder.
Search the drive where the CD files are lying and search for it.
You'll see that sometimes not all 4 would be found - that cool.
Double click on the found images to load it into your main Alcohol screen.
Now you just double click on the first one to mount it and the auto-install screen will appear (like loading a normal cd).
DON'T CLOSE ALCOHOL JUST YET. If the installation requests more than one CD, just mount the images representing the CD (like CD2 or CD3, etc.) and continue.
If you need a serial key - it is usually in the folder of the images, as well as the .exe file that needs to replace the original after installation. If it's available, keep your eyes open for a Windows installation help file - right click on it and open with notepad - it will give you the steps to follow for the installation.
Disco FL launches without the need for a CD....lol...unless you play vanilla, that image is all but pointless being mounted at the moment.:P.
But Victors solution might work.
If it doesnt, burning is probably the only other thing you could try, but if you dont have anything to mount or unmount, its probably not going to work if you do burn them.
Buy a DVD RW if you are experimenting :Dbecause you can clear the data if it doesnt work.
