66497 - Installer does not clean up win registry

Status: VERIFIED FIXED

(SeaMonkey :: Installer, defect)

Description

[Sean Su]

During installation, if Setup installs ontop of a previous Mozilla installation
folder, it should be smart about removing the previous Mozilla's windows
registry entries (both for the install and uninstall keys).

For example, say a machine already has mozilla 0.7 installed, the following
would be the windows registry keys created by the installer for the installer:
  HKLM\Software\Mozilla.org\Mozilla\0.7 (en)
  HKLM\Software\Microsoft\Windows\CurrentVersion\Uninstall\Mozilla (0.7)

If Mozilla 0.8 is installed to the same folder path as Mozilla 0.7, then the
Windows registry would now have:
 HKLM\Software\Mozilla.org\Mozilla\0.7 (en)
 HKLM\Software\Microsoft\Windows\CurrentVersion\Uninstall\Mozilla (0.7)
 HKLM\Software\Mozilla.org\Mozilla\0.8 (en)
 HKLM\Software\Microsoft\Windows\CurrentVersion\Uninstall\Mozilla (0.8)

Setup needs to be able to detect that it installed ontop of Mozilla 0.7 and
remove its obsolete keys.  If it installed into a folder different from Mozilla
0.7, then it should not remove Mozilla 0.7's windows registry keys.
