DllRegisterServer entry point not found: causes and possible solutions

Most of the instructions on the Internet on how to fix DLL errors include the suggestion to copy the file to the System32 or SysWOW64 folder and then use regsvr32.exe to register the file on the system.. And in more than half of the cases, users receive an error message “The dll module is loaded, but the DllRegisterServer entry point was not found. Please check that the file is a valid DLL or OCX file and try again “.

This instruction details the causes of the RegSvr32 error, possible alternatives to fix it in Windows 10, 8.1 and Windows 7, as well as additional information that may be helpful if you need to install a missing DLL on your system.

What entry point is DllRegisterServer missing?

DLL library files are generally sets of program functions, sometimes resources, that can be called from other Windows programs 10 and earlier.

When on the command line as an administrator, enter the command regsvr32 filename.dllThe regsvr32.exe program finds and attempts to call the DllRegisterServer function from the DLL that you specified to register the server, can’t find it and reports an error “DllRegisterServer entry point not found”.

Why is this happening? Because not all DLLs contain this function and not all libraries can be installed on the system using regsvr32.exe, and the recommendations to use the command to register DLLs in many statements are misleading and inapplicable.

How to fix DllRegisterServer entry point not found error when registering a DLL

The following approaches can be suggested to solve the problem:

Try to use the same command, but with additional parameters to install the DLL (spaces before slashes and file name):

regsvr32 / i / n file.dll

Important point at all points: DLL files for x64 systems and 32 bits (x86) they are different even when the name is the same, e inclusive Windows 10, 8.1 o Windows 7 of 64 bits may require a DLL of 32 bits to run some program, and it may not work with a x64 DLL.
