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

[Caldur]

Windows 10 Enterprise N x64

CbB v26.09.0.006

Fresh install without any prior VC++ redistributable packages.

CbB installs four VC++ redistributable packages, three of them are x64, but the one from 2013 is x86.

I fixed it by installing the x64 version of the 2013 VC++ redistributable package (without system restart).

Most probably you will have to replace the x86 one with the x64 to fix the installer.
