PSPad editor Updater doesn't update Versioninfo in Registry

The "PSPad editor Updater" does update all files very well, but doesn't update the version-information in the registry "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\" (and possibly other hives). This leads to the wrong version being displayed in "Apps and Features" and also makes Software-Update-Applications like "uCheck" think its still the old version.

It would be great, if the updater updates the version-information in the registry too.
