Office Communicator 2007 R2 crashes after sign on
After I uninstalled Office 2010 64 bit and installed Office 2010 32 bit I had a problem with Office Communicator 2007 R2.
After entering my password and clicking sign in it crashed every time:
In the EventLog an Application Error was recorded with some additional error info:
Event Type: Error Event Source: Application Error Event Category: (100) Event ID: 1000 Date: 10-3-2011 Time: 15:20:52 User: N/A Computer: remkolaptop Description: Faulting application name: communicator.exe, version: 3.5.6907.221, time stamp: 0x4cddcd9f Faulting module name: KERNELBASE.dll, version: 6.1.7601.17514, time stamp: 0x4ce7bafa Exception code: 0xc06d007e Fault offset: 0x0000b727 Faulting process id: 0xf94 Faulting application start time: 0x01cbdf2e592fc53c Faulting application path: C:Program Files (x86)Microsoft Office Communicatorcommunicator.exe Faulting module path: C:Windowssyswow64KERNELBASE.dll Report Id: 9a4e3adf-4b21-11e0-8f0f-c0cb38a92f9b For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.
The exception code is 0xc06d007e which is defined in WINERROR.h as ERROR_MOD_NOT_FOUND, the error description is: “The specified module could not be found”.
Basically this means that Communicator attempted to load a DLL with a call to LoadLibrary(Ex) and it failed.
So I did a trace with Process Monitor:
So I concluded that mapi32.dll was the missing dll and after obtaining the DLL from another system Communicator worked again.
