how to resolve canon easy print ex with mysql

Also having a Canon printer, 

I get MySQL Server 5.5 on XP/32-bit installed

into C:\Programme\Canon\Easy-WebPrint EX

The reason is a registry setting which should not be there:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\ 

(directly and NOT in a subkey, as it should be)

contains the entries InstallLocation, UninstallString

and a few more that relate to the Canon software.

Just delete 

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\InstallLocation

and MySQL Server installs into the "correct" location.
