That's what I get when I try to use WinRar in Vista on the archive from AB:
I can see the files in the WinRar explorer, but can't uncompress them :/
But you can uncompress it in dosbox as I described, just set mem to 64.
[Edit]
And double clicking them in Vista ... now yeah, it's a dos sfx, says enough :/
[Edit²]
Maybe a reup in plain zip without those rar parts..... ?
[Edit³]
Now, Adamg gonna like this, tried it in 7Zip,
-(was bored)- point it to that csnrgrt.exe, works. 7Zip that can handle those old RAR SFX flawless.
