272871 - [Windows] Updating version without uninstalling leaves Uninstall registry entries

Status: RESOLVED DUPLICATE of bug 247884

(Firefox :: Shell Integration, defect)

Description

[Kyle Hamilton]

User-Agent:       Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0; {6127DDA1-EF94-4E2B-9521-DF4173984DD0}; .NET CLR 1.1.4322)
Build Identifier: 0.92, 1.0PR, 1.0

Updating the version of Firefox that you're running leaves the prior version's 
Uninstall information in the registry.  When I clicked on the older one to 
uninstall it (assuming that it would check for that version's files and see 
that they had changed, and thus skip them), it uninstalled the latest version 
that I had. (I had 0.92, manually updated to 1.0PR, and the Updater auto-
download didn't put a 1.0 option in the Uninstall key.)

Reproducible: Always
Steps to Reproduce:
1. Install an older version of Firefox (0.92 is what I was using), reboot.
2. Install a newer version of Firefox (1.0PR is what I used), reboot.
3. Go to Add/Remove Programs and look for Firefox.  You will see both versions.
4. Uninstall the older version.
5. Cannot start Firefox, the binaries have been removed.

Actual Results:  
Broke Firefox, had to reinstall.  This broke my extensions.

Expected Results:  
Either:
1) Firefox's installer (and updater) should see that an older version of 
Firefox is already installed, and update the Uninstall information accordingly, 
or
2) Uninstalling the older version should see that the binaries have been 
changed, and give the option of deleting them or not.  (less okay)
