I did the following:
- Downloaded zip
- Open zip
- double click on Razen icon (it was in Downloads folder)
Apart from the OS 'you've downloaded this from internet, are you sure', nothing happened. I checked system logs, and couldn't find any errors. I've tried multiple times, I've redownloaded.
I also tried the following:
I tried running from Applications folder, replacing the old version of Razen that was in there. No effect.
I double checked mercurial install
