I’ve just installed this app on Windows 7 x64 after Daemon Tools failed for no reason. (It seems to create two drives but can’t mount anything.) This app has worked fine so far in 1 out of 1 tests. But I can’t unmount the image anymore. When I try to eject the drive, it says it’s still in use and rejects to go any further. Checking with Process Hacker, no process is holding a handle of V: so this can’t be true. There seems to be a bug in it.
