Error with User32.dll

SLaY3R · 24th February 2009, 21:18

When I open Winamp it gives me a error of Entry point could not be located in dynamic link libary USER32.dll. And it also bugs when i try to click on a song to play it.

What version of windows and Winamp are you using?

Windows 9X/ME are no longer supported.

SLaY3R · 24th February 2009, 21:28

I am using Winamp 5.541 and Windows Xp Service Pack 3

What's the exact error message?

e.g. The procedure entry point IsThreadDesktopComposited could not be located in the dynamic link library USER32.DLL

Did you previously install any 3rd-party plugins for Winamp?

Have you tried a clean install of Winamp 5.55

That's the exact message but it does that to more then one program

If that's the exact error message (...IsThreadDesktopComposited...)
then the most likely cause is that some program has erroneously installed files intended for Windows Vista or 7 only under WinXP.

Go to your "C:\Windows\System32" dir

Look for this file:

DWMAPI.DLL

If it's there, either rename it to DWMAPI.DLL.OFF or move it out of the Windows dir to some backup folder elsewhere (don't delete it just yet, just incase).

DWMAPI.DLL shouldn't even exist on WinXP, as it's part of Vista's Desktop Windows Manager.

Now see if you get that error message when opening Winamp and other programs.

If it's not even there, or if the error still occurs,
then it means some other WinXP system file(s) have been wrongly replaced with the Vista version...
and you'll need to use Dependency Walker to try work out what files need restoring.
