Error 430 Class does not support automation

I compiled and built executable of vb6 application that uses Fxscomex to send fax in window 7 . This works well in Window 7 environment but when installed in xp then I get the Error 430.
I have unregistered and reregistered fxscomex dll in xp but the error pesists.
The error occurs at this line:
myFaxser=New FxscomexLib.FaxServer
Any help in resolving this problem will be highly appreciated.

Thanks

Could be as basic as the Win7SP1 ADO bug. Programs using ADO that are compiled under Win7SP1 don't work anywhere else.

You can back SP1 out, rewrite using late binding for all ADO references, or try the "Back Compat TLB" at:

An ADO application does not run on down-level operating systems after you recompile it on a computer that is running Windows 7 SP 1 or Windows Server 2008 R2 SP 1 or that has KB983246 installed

The latter is imperfect according to many reports however.

Others have taken the ADO TLBs from Win7 RTM and force-installed them to Win7 SP1.

Thanks for your response. However, I am not running window sp1. This error only occurs while initializing a dll.
The exact code is as stated below:

Set MainWin.g_objfaxserver = New FAXCOMEXLIB.faxServer

Like I said I have unregistered and reregistered the FXSCOMEX.Dll several times in the xp machine, and it still did not work.

Thanks

try to run the vb6 in xp mode, i believe the error code is 430,

Try installing that and see if it makes a difference.
