Why do I get DllRegisterServer was not found message?

There are a couple of known triggers for this computer error. Among them include the following:

  • The module <file> was loaded but the call to DLLRegisterServer failed with error code 0x8002801c or 0x80070005 – This is usually an issue caused by corrupted DLL files.
  • Entry point DLLRegisterserver was not found – If your DLL files are not accessible to your system, this issue might appear.
  • DLLRegisterserver was not found on Windows Server 2016 – As the error mentions, this issue appears on the Windows Server 2016 edition, and can usually be caused by a system malfunction during the process.
  • Entry point DllRegisterServer was not found on Server 2012 – As in the case of the 2016 edition issues, the system encountered an error during the process.
  • The module isdone.dll/ntdll.dll/kernelbase.dll was loaded, but the entry-point DllRegisterServer was not found – To resolve this issue, simply follow the ISDone.dll Error on Windows 10/11 methods.
