Status: RESOLVED INCOMPLETE

Description

[Simon Porter]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1b2pre) Gecko/20081104 Minefield/3.1b2pre
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1b2pre) Gecko/20081104 Minefield/3.1b2pre

When I start the nightly build of Minefield I get this error message. I am not sure the regression range, I believe it to be at least 6 weeks.

"The procedure entry point IsThreadDesktopComposited could not be located in the dynamic link library USER32.dll. "

Windows XP SP3
Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1b2pre) Gecko/20081104 Minefield/3.1b2pre ID:20081104040308

I get a similar message in a few other apps, Winamp was one but they have since fixed this in the latest release.

Reproducible: Always

Steps to Reproduce:
1. Start Minefield
2. The error will display, click OK
3. Minefield starts and operates normally
Actual Results:  
This error displays:
---------------------------
firefox.exe - Entry Point Not Found
---------------------------
The procedure entry point IsThreadDesktopComposited could not be located in the dynamic link library USER32.dll. 
---------------------------
OK   
---------------------------

Expected Results:  
The error should not display

Google gives 51 results, could you try some of them?

It seems to have something to do with dwmapi.dll
I had this issue with Winamp on a machine running WinXp SP2 and IE 8 installed as well as on a machine with WinXp Sp3 and IE7 installed. Winamp seems to have fixed whatever the issue was though.
This does no happen in FireFox 3 startup.

My user32.dll is version 5.1.2600.5512

I have a dwmapi.dll in c:\windows of version 6.0.5384.4, seems an odd location for it, not sure what put it there.

I renamed the file and the issue is resolved:
http://groups.google.fr/group/microsoft.public.windowsxp.general/browse_thread/thread/ffe00f0300aa94f5

Not sure if this should be resolved fixed if the other users are going to see the same issue with the 3.1 release.

Hi.

I just found this report because this "Bug" also appears on my Machine starting Firefox...

My Version: 3.5 RC2
Mozilla/5.0 (Windows; U; Windows NT 5.1; de; rv:1.9.1) Gecko/20090624 Firefox/3.5 (.NET CLR 3.5.30729) Creative ZENcast v2.00.14

In my case I found the file at C:\WINDOWS\system32\dwmapi.dll (also Version 6.0.5384.4). I'm running WinXP Home SP3 with IE8 installed.

Is this the right place for this Bug or should it be entered as new?
