668331 - System Integration dialog on Windows 7 leads to Program Compatibility Assistant dialog

Status: RESOLVED WORKSFORME

(Thunderbird :: OS Integration, defect)

Description

[Travis Heath]

User Agent: Mozilla/5.0 (X11; Linux i686 on x86_64; rv:5.0) Gecko/20100101 Firefox/5.0
Build ID: 20110615151330

Steps to reproduce:

Conditions:
   Windows 7
   User Account Control enabled (Default - Always notify me)

Steps to reproduce:

1.)   User Alice installs Thunderbird, accepting all defaults including the final prompt to set Thunderbird as default email client
2.)    User Bob later logs in, runs Thunderbird for the first time and is prompted to set Thunderbird as default email client.



Actual results:

    Upon clicking Okay to the set default client prompt, WIndows 7 will display a Program Compatibility Assistant error saying that Thunderbird Helper (helper.exe) might not have been installed correctly
 
   Windows 7 recomends User Bob reinstall with recomended settings, and gets prompted to elevate privileges.

It does appear that HKCU\Software\Clients\Mail\(Default) = "Mozilla Thunderbird" get set.


Expected results:

Helper.exe should not trigger a Program Compatibility Assistant and an standard, non-administrator user should not have to face an elevation prompt to just set their preferred email client.

We recently fixed something similar - can you double check and let us know if this is fixed in Thunderbird 13 ?

I've not been able to reproduce the bug in any recent version of Thunderbird.  That's over an install base of around thirty users and in each case the user lacks administrator privelege, is not the same account that installed the software, and has UAC enabled on their computer.  We would have heard something even if I missed it in testing.  If my memory is correct, we only saw this bug in the one released version of Thunderbird 5.0.

Thanks.
