Call To Dllregisterserver Failed With Error Code 0x80040200
Contents |
Development > Visual C++ Question 1 Sign in to vote I have a legacy MFC C++application that was compiled on XP with call to dllregisterserver failed windows 7 Visual Studio 9 on XP. The application works on XP and call to dllregisterserver failed with error code 0x800 has an installation package. When I install it on Windows 7 everything works except one OCX designed to was loaded but the call to dllregisterserver failed with error code 0x80070005 provide some DCOM capabilities - it fails with an error message indicating that there is an invalid class string. This does not happen on XP. Having seen this error before the module was loaded but the call to dllregisterserver failed with error code 0x80070005 I tried to register the OCX in question and that did indeed fail with the error message "xxx.OCX" was loaded but the call to DllRegisterServer failed with error code 0x80040200 The installation package did not report any errors and when I tried to register the OCX manually I was logged on as the administrator. As the Windows 7 PC is
Call To Dllregisterserver Failed With Error Code 0x80004005
not a development machine I have little debugging capabilities on it and I would not know how to set about debugging the regsvr32 failure anyway, but if I run code that utilizes the OCX in question I see that the OCXis instantiated and only fails when it attempts to connect with my main application using something like: pOe = new COleException; m_IMyInterface.CreateDispatch(_T("MyApp.Document"), pOe); The MyApp.Document application seems to be fine and updates the registry for MyApp.Document so that it should be available for creation by CreateDispatch and although this works on XP it fails on Windows 7 – however I do not see why that should cause theOCX to fail to register. Although the ocx fails to register it seems to be available as an ocx because it instantiates and only fails when attempting to create an instance of the main application. All applications dll etc. reside on the same PC. Any thoughts on how best to tackle this? Thank you. Edited by ellipsisware Wednesday, September 22, 2010 2:13 AM OCX not OCV ln4 Wednesday, Septem

Call To Dllregisterserver Failed With Error Code 0x8002801c
DllRegisterServer in cdosys.dll failed. Return code was: 0x800704da The module "cdosys.dll" was the module actxprxy dll was loaded but the call to dllregisterserver failed loaded but the call to DllRegisterServer failed with error code 0x80040200 ENVIRONMENT VIPRE Email Security Microsoft Exchange regsvr32 return code 0x80040200 2003 SOLUTION If you get the error "DllUnregisterServer in c:\windows\system32\cdosys.dll failed. Return code was: 0x80040200" it simply means that the DLL cannot get unregistered because it is already https://social.msdn.microsoft.com/Forums/vstudio/en-US/e4256b55-3928-46a4-b80e-3ae10b7661ac/error-code-0x80040200?forum=vcgeneral unregistered.If you get the error "DllRegisterServer in c:\windows\system32\cdosys.dll failed. Return code was: 0x800704da", it means that something else is registered in its place. This is typically going to be cdoex.dll. You should be able to fix it by following these steps: Unregister cdoex.dll with this command: regsvr32 /u "c:\program files\common files\microsoft shared\cdo\cdoex.dll" Register cdosys.dll with this command: regsvr32 https://support.threattracksecurity.com/support/solutions/articles/1000071002-error-0x80040200-or-0x800704da-when-trying-to-register-or-unregister-cdo-dll-s "c:\windows\system32\cdosys.dll" Re-register cdoex.dll with this command: regsvr32 "c:\program files\common files\microsoft shared\cdo\cdoex.dll" CAUSE CDO DLL's are used by applications to communicate with databases, such as for reporting and quarantine. Both cdosys.dll and cdoex.dll contain commands to access them, but are slightly different. Programs will fail when trying to issue certain commands using the DLL's if the wrong one is referenced in the registry. cdoex.dll will sometimes get registered in locations in the registry where cdosys.dll should be. At this time it is not known why, but it is suspected to be either because of another program that uses CDO communication (with databases) or a Windows update re-registers the entries improperly.
