How do I resolve Run-time error 429 ActiveX component can t create object

Question

My company has a VB6 application using Crystal Reports 7 which a client has asked to be installed on Windows 7 32 bit  It is currently installed on Windows XP 32bit SP2 machines at the client  Connection to the DB is done via ODBC to SQL Server 2000 instance on another server   On Windows 7  the installation works fine  however when you try to open the application  the error is given   I have looked at the following    Registering all the dll s and ocx files using regsvr32  Some will not register as they either are registered already or the following message is given  Make sure that   name  dll  is valid DLL or OCX file and then try again   I read this forum thread regarding this  http   social msdn microsoft com forums en-US vblanguage thread 0653f685-4526-45d9-89f3-8c479a6b4c62 Monitored the opening of the application using a ProcessMonitor application to try and spot if there is a missing dll or ocx file - this does not seem to be the case  Reviewed the application according to this list and nothing seems to be against these guidelines   I ve noticed two items in the knowledge base that relate to this   http   support microsoft com kb 281848 - the comdlg32 ocx bundled with the application is version 6 0 81 69 and the one in the system32 folder on the dev machine  WinXP 32 bit  is 6 1 97 82  However if this was the issue then surely it would not work currently   http   support microsoft com kb 184898 - I m not sure how to confirm that this is the issue   Finally  due to complexities  I am not allowed to make code changes to this application  Even if I was  I m not a VB6 programmer  just the guy who got the terribly support project  If code changes are required  then I ll have to investigate using WinXP mode   Update  I get the same error in XP Mode  That s a Win XP with SP3 VM  This runs on a Win XP SP2 VM  is there potentially something in SP3 that would have caused this to occur  Or is it just a fact of it being XP Mode

The file msrdo20 dll is missing from the installation   According to the Support Statement for Visual Basic 6 0 on Windows Vista  Windows Server 2008 and Windows 7 this file should be distributed with the application   I m not sure why it isn t  but my solution is to place the file somewhere on the machine  and register it using regsvr32 in the command line  eg   regsvr32 c  windows system32 msrdo20 dll   In an ideal world you would package this up with the redistributable

You say it works once you install the VB6 IDE so the problem is likely to be that the components you are trying to use depend on the VB6 runtime being installed   The VB6 runtime isn t installed on Windows by default   Installing the IDE is one way to get the runtime  For non-developer machines  a  redistributable  installer package from Microsoft should be used instead   Here is one VB6 runtime installer from Microsoft  I m not sure if it will be the right version for your components   http   www microsoft com downloads en details aspx FamilyID 7b9ba261-7a9c-43e7-9117-f673077ffb3c

I got the same error but I solved by using regsvr32 exe in C  Windows SysWOW64  Because we use x64 system  So if your machine is also x64  the ocx dll must registered also with regsvr32 x64 version
