Bug #42423	Windows x64 installer creates registry in WOW6432Node

Description:
I just ran the 64-bit installer.  After installing, I went to check for the registry setting (which Python-Mysql needs to locate the installation), but found it wasn't where I expected it (HKLM\Software\MySQL AB).  It was, however, found in (HKLM\Software\Wow6432Node\MySQL AB).

This is probably an unintended artifact of the installer being a 32-bit application and so when it mounts HKLM\Software, Microsoft subtly replaces the key with the WOW6432Node key.

How to repeat:
Install mysql-5.1.30-winx64.

Suggested fix:
Either build the installer as a native 64-bit application, or search the API to find if there's a way to have the 32-bit installer write to the 64-bit (native) section of the registry.

Thank you for the bug report.

I just confirmed this problem (originally reported against 5.1.30) persists with the latest MSI installer (mysql-5.1.43-winx64.msi, md5 4608343b3fa94304d3b6928fa3a3af31).

Still a problem with 5.5.14, affecting not only Python but also RMySQL.

Thank you for the bug report. We are closing this report now for two related reasons:
* MySQL Server 5.1 is an obsolete version of MySQL Server
* For recent MySQL Server versions, the config wizard is no longer available, and the MySQL Installer for Windows is the recommended way to install MySQL Server on Windows
