impossible to install dll and ocx on system32

[Mustaphi]

Hello VbForums
On one of my clients system (W10 professional) I was unable to install VB6 common controls on system 32.
I tried to copy them manually but impossible to register them by means of regsvr32
Is there a workaround please?
I have already installed the application on more than 20 systems before.
thank you

Are you using a Windows Installer package (.MSI)? An old fashioned PDW setup package? A No-No-Setup script?

There isn't a lot to go on here. "Don't work, please help" isn't very descriptive.

Why on Earth would Windows 10, Pro or otherwise, be a factor here?

Is it a 32bit or 64 bit version of Windows?

I'm using Setup Factory installer

I'm not sure but I think it is 64 bit

If the ocx is 32bit, you have to register with the regsvr32 in SysWOW64 unless your windows install itself is 32bit (rare now, even people still using XP mostly use 64bit XP).

I've always just opened a command prompt window and typed regsvr32 without wondering what folder it was executed from and it always "just worked"...

I've always just opened a command prompt window and typed regsvr32...

And that command-prompt needs to be started "As Admin" of course...
(since there's COMponents out there, which require registry-entries in HKLM)

thank you all
But still no one told me why these ocx and dlls refuse to be installed on this special machine.
IS there a way to force windows to accept installing these dlls in system32 or
SysWOW64?
thank you

What messages, if any, are you getting when you try to register them? What anti-malware software is running on the system?

Yesterday how to try all can not restart also can not, today is good, can register DLL successfully, strange

During the process of installing the application I get a message error like:
impossible d'enregisrer l'objet com(ActiveX)
C:\Windows\system32\MSCOMCTL.OXC
echec dans Loadlibrary (126)

Your (32Bit) OCX-library was placed in the wrong directory -
and is trying to load its "flat-dependency" (comctl32.dll) in a 64Bit-version (from within the same folder: \sytem32\).

You can fix that, by placing your 32Bit-OCX in the right folder (where all other 32Bit-Dlls are located):
\SysWow64\

It is useful to develop an administrator rights registration tool, such as set to handle all OCX,COM DLL default openers.
Open will automatically register successfully, and display a window for 3 seconds, you can choose to uninstall, register 64-bit DLL, generate. NET DLL and TLB files, unregistered TLB files.
Try unregistration and then load without registration if it succeeds.
This will solve all the registration problems of DLL and OCX.
Do not know 64 bit free registration loading DLL function to achieve?
