Error Popup


Recommended Posts

I recently updated my Advanced WindowsCare V2 to Version When I run it I get the pop up shown in the thumbnail.


This happens as AWC2 is loading and just as the program opens the main page. When I click on ok the popup goes away. And it seems that the program works. I have only scanned a few things, but have been afraid to fix anything because of the error.

Hi oldsalt35,


The reason is, some MS packages (including Office XP) install a DLL named APPHELP.DLL although they should not. This DLL is XP-specific and should not be installed on Windows 2000.


If present, the DLL is loaded by these applications. The problem is that APPHELP.DLL looks for an entry in NTDLL.DLL (RtlDuplicateUnicodeString) that doesn't exist in Windows 2000.


Just rename (or delete) APPHELP.DLL (it's in SYSTEM32) and you'll get rid of the error message.


I hope this helps.
