How to call PDF to Text Converter SDK/COM from both 32bit and 64bit applications? How to use PDF2TXTCOM.exe COM interface?

Greetings

My name is John. I work as a developer in a Danish company. I have been using your licensed version of pdf2txt for some time now, but now I have this small particular problem.

When trying to run my application in 32-bit mode on a 32-bit OS, I receive the following error:

"Retrieving the COM class factory for component with CLSID {-4022-457E-90EB-B0C619919C9E } failed due to the following error: 80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG))."

Do you have any suggestions for me?

It did not work

I use Visual Studio 2012 and develop in c#.

What I am doing is the following:

I create a new project
I add the file "pdf2txt.dll" as a reference
I add the following line to the code: "PDF2TXT.CPDF2TXT pdf2txt = new PDF2TXT.CPDF2TXT();"

The error appears in the line above when I run my application in x64 platform target, but not when I run x86.
