CorelDRAW X3 C# ASP .NET COM class factory Factory Error

Hello,

I am writing a web application in C# and ASP .NET. I have added a reference to the the CorelDRAW X3 .tlb and am doing conversion of uploaded .cdr image files to .png and .pdf for display on the web.

This all works fairly well when the application runs in the VS debugger, but when I push the application out to a production webserver I get the following errors:

Retrieving the COM class factory for component with CLSID {4A110001-2109-4B5D-BC63-17AE8914E384} failed due to the following error: 80070005.

Retrieving the COM class factory for component with CLSID {4A110001-2109-4B5D-BC63-17AE8914E384} failed due to the following error: 80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)).

I granted permissions to the web user (IUSR) in IIS 7.5 using the DCOM Config tool in Component services and got it working for a bit on my development webserver, but then I made some changes and am having trouble again. I cannot seem to get this working on the production server which uses a newer version of plesk.

Does anyone have insight into how to troubleshoot this issue?

Thanks!

I ran across this same error and noticed this thread was not replied to with an answer so I wanted to share my findings.

The error: Retrieving the COM class factory for component with CLSID {12C10081-3D51-9CAB-4669-130BF27EB0CE} failed due to the following error: 80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)).

After extensive logging and debugging I found this line to be the culprit:
VGCore.StructExportOptions exportOptions = new VGCore.StructExportOptions();

What is interesting is the error comes after other successful processes such as
VGCore.Document openDocument = CorelDrawApplication.OpenDocument(documentToOpen, 1252);

This was running fine on my local machine and only received the error after a VS publish to Windows 2012 server with CorelDRAW X7 installed. The issue was that CorelDRAW installed under "The Interactive User" instead of "The Launching User" which meant my IUSER account could not run the application resulting is an unregistered com reference. Why it failed on VGCore.StructureExportOptions instead of earlier, I have no idea.

To RESOLVE, run DCOMCFNG.EXE, DCOM Config, CorelDRAW, Properties, change to "The Launching User".

Thanks much, Craig
