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
If these keys are used, the DllRegisterServer procedure will not be searched, but DllInstall will be used. But it may not be in the file either, and this is normal.
- Find out what kind of DLL file it is and install it correctly, generally as part of a set of components that contain that file, whenever necessary. What do you have in mind? As an example, problems with files whose names begin with msvc often require installation of the correct version of Visual C distributed components ++ (and x64 systems often require the installation of the x86 or 32 bits), in the For files called dx, missing DirectX libraries must be installed with Microsoft web installer, and for unarc.dll files, ISDone.dll is generally not required to install any files and is not intended for them.
- Sometimes, the following method can work: just copy the .dll file to the same folder as the .exe file of the program or game reporting the error.
- Use my site search, specifying the name of the DLL that is causing the error; for most of the most common, I have detailed instructions that indicate which components to install.
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.
