MySQL installation error – The wizard was interrupted before MySQL Server 5.1 could be completely installed

I had to install a WordPress installation on IIS last week (I really would not recommend this is done – a linux install is so much easier) and part of that installation requires the install of MySQL for the database. The most current version is 5.1.35 but unfortunately there is a big bug with the install. It completely fails to install with the error message of “The wizard was interrupted before MySQL Server 5.1. could be completely installed.” With no useful explanation in the dialog box, event viewer or installation log files it is extremely hard to work out what is wrong. The solution for the time being is to download the 5.1.34 installation. The windows version is available at filehippo. It doesn’t help that the official MySQL web page does not link to previous versions of the software either. After logging a “me too” comment on what now seems to be the official bug report at MySQL Bugs – #45418, the number of people with the same problem has increased dramatically.
I had to register with the MySQL website to log my bug and they sent me an email a couple of days later mentioning the release of the new software (that has the problems) – rather annoying as it’s not a good idea to publicize software that doesn’t even install. I tweeted my comment that they should fix the issue before emailing out and I got a reply that they are aware of the problem and are working on it. No post has been added to the bug report though.

    Hi, I ran into the same problem – and was frustrated that no previous versions could be found on the official MySQL website too … The FileHippo file installed successfully, and the service is running smoothly!
