I'm not sure what's going on for me - I just used the Calibre link to download the latest version 2.58.0, and when I go to run it I only get the options to: Change, Repair or Remove.
The first pic below is the Set up wizard version I get. Note, I get a double setup version box, but this one supersedes the first one which appears for less than a second on my screen.
The second pic shows what happens after I press 'Next'.
So, the first time through I chose 'Repair' and then continued.
The update install didn't take place so I tried to install again but keep getting this same Change, Repair, Remove box ......
I'm using Win 7 and nothing has changed between the last Calibre install update and this one ....
