Artrage 5 install problem

[markw]

I think the problem here is not with the Installer being corrupted but rather with how macOS, after Catalina, interoperates the installer.
I can download AR5's installer, open it and install AR5 onto my 2017 MacBook Pro which is running Catalina as my main work OS.
But if I boot into my Ventura drive on the same MackBook Pro and try the same thing again, I get the warning message about no “mountable file systems” when opening the installer.
I’m not too surprised by this myself as AR5 and it’s installer were written long before Big Sur and it’s descendants came along and the internal architecture from Big Sur onwards is very different now to how it was back in the day when AR5’s installer was written.
I can say though that my version of AR5 that was migrated over to my Ventura drive dose seem to run, but how stable it would be to work with is something I've not explored in any depth.
So could the installer for AR5 be rewritten to work with newer macOS’s? Possibly… but I don’t know.
But I really doubt if it would be considered a cost effective use of time and resources to do so for such an old version of AR. Especially if the app itself were not even able to run on the M series of chips, even if it could be installed.
