Error retrieving the com class factory RRS feed

  • Question

  • I am installing an ERP. One of the piece which runs under IIS calls a 32 bit dl.  I made sure I enabled the "Enable 32 bit application" on all the application pool. I am using IIS 8 which is running on Windows server 2012. I have very little knowledge about IIS but I am not an expert.  I have installed the same ERP for my another client on the windows server 2012 without any issue.  Here is what I see when I try to access the webpage.  I have been struggling with this issue over 2 days now. Any help will be appreciated.

    Retrieving the COM class factory for component with CLSID {940779FA-1BE7-4BAC-9691-6A786642779B} failed due to the following error: 80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)).

  • Hi Bharathi B,

    This forum is discussing and ask questions about .NET Framework Base Classes (BCL) such as Collections, I/O, Registry, Globalization, Reflection. Based on your description, I am afraid this is out of our topic here, and your case more related to IIS. I would suggest you using the following forum, please repost this issue in that forum for better support. Thanks for your understanding.
