211723 - Mozilla 1.4 crashes on install over top of 1.3, even if 1.3 is uninstalled

Status: RESOLVED DUPLICATE of bug 195600

(SeaMonkey :: General, defect)

Description

[Gordon Cormack]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.4) Gecko/20030624
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.4) Gecko/20030624

When I install Mozilla 1.4 on a system that previously had 1.3 installed, 
Mozilla fails to launch.  The error message says that xpcom.dll crashes.

This install fails whether or not you uninstall 1.3.

The workaround is to remove 'Program Files/mozilla.org' before installing 1.4.

Here are the files that were lurking in the deleted folder.  Clearly one of
them is the culprit.  In any event, the installer should deal with this.

Reproducible: Always

Steps to Reproduce:
1. Install old version(s) of Mozilla and various plugins 
2. Install 1.4  (Mozilla crashes when launched by installer)
3.  Try to run 1.4  (crashes on startup)

Actual Results:  
xpcom.dll crashes

Expected Results:  
installer should have cleaned Program Files/mozilla.org 

I cannot detail exactly what versions of Mozilla and what plugins were installed
on this computer.  All I know is that in the state it was in, it could happily
re-install 1.31, but the install of 1.4 crashed every time.

After removing Program Files/mozilla.org the install worked OK.
