I don’t as a rule mess with permissions, but I did make that folder as “me” and I’ve never had troubles launching anything from there including other Audacity Versions. I have more than one machine with that system release. I’ll check.
I know what happened even if I can’t reconstruct the entire performance. All the permissions between the two machines are identical (by actual count). The “Office Machine” (Mini) has a different installer.
Note the disk image file size.
I know I can get that by trying to move the “image” file into position before the system is finished downloading, and the completed download (different file) does install, but that doesn’t account for my moving the broken installer to the desktop and having it succeed. It doesn’t this time. Further, the machine objects strongly to me doing anything of the sort.
I was surprised you found a second, independent instance of this oddity.
I should also pay attention to the install times and dates. I don’t remember which machine was first.
Sometimes when troubleshooting, I’ll take the problem upside down: If someone wrote me a generous check, how would I intentionally cause this problem. I’m pretty sure I know how I got the first part of this, but not the second.
When I download the 2.2.0 Disk Image, it looks like this (click the image. It’s tall.)
The .PART file is the actual digital download. The .DMG is a pretty placeholder (as far as I can tell). The download activity graphic is a four pixel blue arrow in the top menu bar. I know it’s there and I can’t find it.
I have a relatively neat desktop, but if you don’t, like most of my right-brain creative friends, the .PART could be anywhere in your vast screen leading you to think the zero byte .DMG is the real thing. So pull that over to the local version archive and discover it won’t install.
Meanwhile, the download completes and your desktop looks like this (click the pix)
You drag your dud to the desktop. I have my desktop set to snap icons into a neat grid, and that’s not unusual so it would be easy to lose the dud in the forest of other icons. This time when you double click the .DMG file, you’re clicking on the actual installer and the installation goes normally.
