293866 - Updating to 1.0.4 removes old version entries in Add/Remove Programs but not system wide

Status: VERIFIED DUPLICATE of bug 294357

(Toolkit :: Application Update, defect)

Description

[Matthew Notley]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.8) Gecko/20050511 Firefox/1.0.4
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.8) Gecko/20050511 Firefox/1.0.4

I have found that versions 1.0.3 and 1.0.4 have updated and removed the old
version entries from Add/Remove Programs, but they still appear system wide.

Example:
When installing Macromedia Flash Player and Macromedia Shockwave Player, the
Macromedia installations asks which browsers to install the players into. It
lists Internet Explorer 6 and versions 1.0.2, 1.0.3 and 1.0.4 of Firefox. This
must mean, when updating Firefox, it only removes the entries from Add/Remove
Programs, not system wide.

Reproducible: Always

Steps to Reproduce:
1. Install Firefox 1.0.3 followed by 1.0.4, you will notice it removes the old
version number from Add/Remove Programs.
2. Install Macromedia Flash Player or Macromedia Shockwave Player, you will
notice the old version numbers are not removed from this list.

Actual Results:  
Old Firefox version entries still appear system wide. They are only removed
properly from Add/Remove Programs list.

Expected Results:  
Firefox should remove old version entries system wide.

I think Macromedia is reading all entries it can find in 
HKEY_LOCAL_MACHINE\SOFTWARE\Mozilla , while it should examine 
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall instead.
That last one is used to display the entries for Add/Remove Programs. The
Firefox installer removed the old entries in latter, but leaves them in the
former location. Bug 247884 talked about it, but I think they're left behind to
support multiple side-by-side installation (you would have to install/uninstall
manually though).

Macromedia is apparently trying to install its plugins in all versions. That's
not too bad, but it should have noticed that they all point to the same location
(C:\Program Files\Mozilla Firefox), so the older entries are bogus.
