Unable to register the DLL/OCX: RegSvr32 failed with exit code 0x3

Hi, I just tried to install the 2.48 version and got the following error message during installation.

What I have tried: Uninstalled older version, cleaned leftover registry keys, restarted PC, re-installed with all apps and folders closed. It would always give me the same message. Version 2.47 installs without issues.

Please advice.

I have windows 10 home x64

What will happen with XnViewShellExt.dll?

It seems that you need to reboot your system, and try again

I have tried that. Same message. Doesn't happen with previous version.

I can't reproduce on Windows 10 x64.

Do you use XnViewShellEx? Do you have installed before the standalone XnShellEx package?
The version of ShellEx in the XnView package is for Windows 32bits not 64bits

I didn't have it when all these happened, but because of this issue, I looked it up and installed separately the x64 to try it. But as I said all the issues where present before separately installing it.

could you try to re-download the 2.48 setup, and install it?

Hi and sorry for the late response (I have been really busy). Although, I had already tried downloading the installer again and hadn't worked, this time it worked and the installation completed successfully. I don't know if the installer was changed or if by installing XnViewShellEx separately helped. Thanks a lot for your help.
