On Windows 8 and newer it should be possible to mount the ISOs just by double-clicking.
Discussion
It is (luckily for me), but I have to do it every time I turn it on. And since I have the isos somewhere stored, it's just annoying to find and open them both. I remember Daemon just sinply kept them mounted after turning pc on.
True, now that you say it, I remember too π
I recently downloaded an older version of Daemon tools, I think it was from archive.org
Maybe this one π€ https://archive.org/details/daemon347
I do not know if that works on recent windows versions though..
