It looks like the installer itself didn't get the version number updated correctly, so the *installer* resources (ie: version resources only) say 2.45. Running the installer says 2.50, and everthing that gets installed is 2.50. It's just an issue with the version resources on the installer.

We just updated the installer, but the only change is the installer version resource, which isn't used during the install or after the install at all, so if you have the binary from earlier today or yesterday that reports 2.45 when you look at the version resources, you don't need to install a new one - it's the same thing.

Thanks for the report,
Pete
