I try to register a COM component in new Windows Server 2012 R2 with REGASM and don't get any errors. However, the COM class doesn't get registered.
On my developer computer, this class is registered successfully. I don't understand what is going wrong on this server, because I made COM components for years, hundreds of times.
Usually I mark interface in the same way
<Runtime.InteropServices.ComVisible(True)>
<Runtime.InteropServices.Guid("65E58463-DB6F-421A-8DE4-A2CE106A7554")>
<Runtime.InteropServices.InterfaceType(Runtime.InteropServices.ComInterfaceType.InterfaceIsDual)>
And mark implemented class as
<Runtime.InteropServices.ComVisible(True)>
<Runtime.InteropServices.Guid("8421A6EE-9101-4119-9262-556B6A45D28B")>
<Runtime.InteropServices.ClassInterface(Runtime.InteropServices.ClassInterfaceType.AutoDispatch)>
<Runtime.InteropServices.ProgId("TDS.DbMail")>
This class I wrote with .NET Framework 4.8, it installed on the server successfully. Attempt to change 32/64 version of library is not successful, either.
Can anybody share any advice with me?
