c# - HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG))

Question

I am building a GIS Application but whenever I run the code it's giving me this error

System.Runtime.InteropServices.COMException was unhandled Retrieving the COM class factory for component with CLSID {FBF5715D-A05D-11D4-A64C-0008C711C8C1} failed due to the following error: 80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)).

Also, in the Project Properties the Option for Register For COM Interop is disabled.

This could also be an issue of building the code using a 64 bit configuration. You can try to select x86 as the build platform which can solve this issue. To do this right-click the solution and select Configuration Manager From there you can change the Platform of the project using the 32-bit .dll to x86
