K-Lite Codec Pack Mega Installation Problem Empty K-Lite Codec Pack Mega Installation Problem

Hi,
During few years, I have error messages during installation K-Lite Codec Pack Mega.

The error says:
Unable to register the DLL/OCX:RegSvr32 failed with exit code 0x5.
Unable to register the DLL/OCX:RegSvr32 failed with exit code 0x800700C1.
There are three options:
Try again
Ignore the error and continue (not recommended)
Cancel installation

If I try again, it doesn't work.
Ignoring the files that cause the problem is the only solution.

The files that cause the problems are:
LavAudio.ax, LAVVideo.ax, LAVSplitter.ax, MpcVideoRenderer64.ax, BassAudioSource64.ax, MPCImageSource64.ax, ffdshow.ax (code 0x5 error)
madVR64.ax (code 0x800700C1 error)

I tried to install LAV Filters separately, I got same LAV .ax errors.
I ran installer as "Run as Administrator". It didn't work. I tried to install it in safe mode. I got same errors.

I've installed all files related to Microsoft Visual C++ Redistributable Version, such as vc_redist.x64.exe, vcredist_x64.exe, vc_redist.x86.exe, vcredist_x86.exe.
They didn't make any differences.

I'm out of options.
If you can help me anyway, I'll appreciate.

Here are some screenshots:

The installer already runs as administrator by default. It also does not need any redists or other dependencies.

Error code 5 means access denied. So possibly your virus scanner is blocking things.

Or something is wrong with your Windows installation. Run these commands from admin command prompt:
dism /online /cleanup-image /restorehealth
sfc /scannow

0x800700C1 means "not a valid Win32 application".
But that can also happen when verifying its digital signature fails.

So yeah, something is likely broken on your system.
