Version 0.5.2 install issue on Windows 7 (minor issue)

[BrightAnarchist]

I had version 0.5.1 installed, and then I downloaded and installed version 0.5.2. I ran Bitcoin-qt, and when I click about, it says that it's version 0.5.1.

So I simply uninstalled 0.5.1 and installed 0.5.2, problem solved.

But I'm not sure why the installer wouldn't overwrite the older version.

If the executable was locked at the time of installation (due to av-scanning or whatever else the system may have been doing), any installer would ask the OS to replace the locked file at next boot.
It's a shame you didn't just reboot.
I have 5.1 on a few machines, I'll mess around with the installer a little bit and report back.
