It's not Rev, it's WinRAR co-opting the '.rev' extension for its own use
(for "RAR Recovery Volume"). Apparently uninstalling WinRAR doesn't remove
the extension adjustment that was put into the Registry by the WinRAR

To fix this, you'll need to go into RegEdit, into HKEY_CLASSES_ROOT (HKCR)
and hunt down the ".rev" key. Clicking on it will show that the default
value for the .rev key is "WinRAR.REV", which in turn points to the
WinRAR.REV key in HKCR. Opening that, and expanding "shell", then "open",
then "command", you'll see that the default value is the path that points to
the WinRAR executable.

Sinc RunRev apparently doesn't install a key in HKCR for Revolution (or at
least, I can't find one on my PC), you'll have to do this:

1) Change the 'HKCR\.rev' default value to "Revolution" instead of

2) Create a subkey under HKCR for 'Revolution', then a subkey under
'Revolution' for 'shell', then a subkey under 'shell' for 'open', then
finally a subkey under 'open' called 'command', and then set the value of
the 'HKCR\Revolution\shell\open\command' key to the path to Revolution, like

   "C:\Program Files\Revolution 2.6.1\revolution.exe" "%1"

Then close the Registry. At this point, the .rev files will still show the
RAR icons, but 2x-clicking on them will launch Rev. If you log out and log
back in again (or reboot your PC), the icons will now display as Rev icons.

I hope someone at RunRev is going to call the guys at WinRAR and try to get
some kind of settlement over the .rev extension...
