Every couple of years or so, it comes time for me to look into getting a different virtual cd/dvd software. I used to always use Daemon tools lite, but at some point, it gave me problems. Sometimes because of it's intrusive installation process, rebooting and all that. it feels like it's installing in a more complicated way than necessary. Then, it couldn't read certain images (this is years ago, to be fair). So I moved to PowerISO's virtual drives, which I was happy with. But that isn't free, so I eventually needed another one. So I got Elby's Virtual Clone Drive. I've been using it for a couple of weeks, and I find it not very stable. It will often sort of disconnect the loaded image, even though it still shows it as mounted. Then I remount it or reboot, and it works fine again. but it's annoying.
Now, I'm going to try this free WinCDEmu, which may or may not be good. If all these don't work, I'll go back to Daemon or PowerISO.
