Register comdlg32.dll gets Regsvr32: DllRegisterServer entry point was not found

Question

I have Windows 7, 64-bit.

I\'m trying to register a .dll (comdlg32.dll) using regsvr32. But I get an error that says the dll is read but the DLLRegistryServer entry

Answer 1

SOLUTION OF Regsvr32: DllRegisterServer entry point was not found,

1. Go to systemdrive(generally c:)\system32 and search file "Regsvr32.exe"
2. Right click and click in properties and go to security tab and click in advanced button.
3. Click in owner tab and click edit and select administrators and click ok.
4. Click in permissions
5. Click in change permissions.
6. Choose administrators and click edit and put tick on full control and click ok.
7. Similarly, choose SYSTEM and edit and put tick on full control and click ok and click in other dialog box which are opened.
8. Now .dll files can be registered and error don't come, you should re-install any software whose dll files was not registered during installation.

Answer 2

comdlg32.dll is not a COM DLL and cannot be registered.

One way to confirm this for yourself is to run this command:

dumpbin /exports comdlg32.dll

You'll see that comdlg32.dll doesn't contain a DllRegisterServer method. Hence RegSvr32.exe won't work.

That's your answer.

ComDlg32.dll is a a system component. (exists in both c:\windows\system32 and c:\windows\syswow64) Trying to replace it or override any registration with an older version could corrupt the rest of Windows.

I can help more, but I need to know what MSComDlg.CommonDialog is. What does it do and how is it supposed to work? And what version of ComDlg32.dll are you trying to register (and where did you get it)?

Have you unistalled your Internet Explorer? I did, and I had the same issues, if so, you have to:

1. Reactivate IE (Control Panel -- Programs and Features -- Turn Windows features on or off).
2. restarting the computer
3. (important!) running Windows Update to get all available updates for Microsoft Explorer
4. restarting the computer (again)

Finally it works!

Answer 4

Information about missing entry point error installing legacy VB6 compiled applications on Windows 10 which I hope could be useful to someone.

Missing OCX files can be found in the "OS\System folder" of the Visual Basic 6.0 installer package. Today I copied the relevant OCX file (from our network) to the local computer

And then I typed the commands below, as administrator, which normally work to register it.

cd \windows\syswow64
regsvr32.exe /u mscomctl.ocx
regsvr32.exe /i mscomctl.ocx

(add the path to the locally copied file for the /i command)

However today I got errors from both these regsvr32.exe commands.

The second error was giving the DllImport missing entry point error which is similar to the error mentioned by the original poster.

To resolve, one of the things I tried was leaving out the switch -

regsvr32.exe mscomctl.ocx

To my surprise it then said it was successful. To confirm, the application started up properly afterwards.

I have faced the same issue with COMDLG32.OCX and MSFLXGRD.OCX in Windows 10 and Visual Studio 2010. It's an MFC application.

Then I downloaded its zip file from the google after extracting copy them at following paths:

C:\Windows\System32 (*For 32-bit machine*)
C:\Windows\SysWOW64 (*For 64-bit machine*)

Then run Command Prompt as an Administrator then run the following commands:

For Windows 64-bit systems c:\windows\SysWOW64\ regsvr32 comdlg32.ocx
c:\windows\SysWOW64\regsvr32 msflxgrd.ocx (My machine is 64-bit configuration)

For Windows 32-bit systems c:\windows\System32\ regsvr32 comdlg32.ocx

c:\windows\System32\regsvr32 msflxgrd.ocx

On successfully updation of the above cmds it shows succeed message.

I also had the similar problem while registering myinfo.dll file in windows 7. Following work for me: Create a short cut on your desktop C:\Windows\System32\regsvr32.exe c:\windows\system32\myinfo.dll right click on the short cut just created and select as Run as administrator.
