I have been a long time Nisus user on Mac OS 9 and I just got a new computer with Mac OSX. I wanted to try out the Nisus writer for OSX and downloaded the demo Nisus Writer 2.1 Express installer, however when I tried to open the file I got an error message "The following disk images failed to mount [image] NWX-v212.dmg [reason] no mountable filing systems". Do you have any suggestions.
The disk image was likely corrupted during download. You should try downloading the file again. If the download completes properly, the file should be about 20MB in size.
