DLL errors when starting after a clean re-install

[jweaver]

I really hope this isn't a stupid problem.. Sorry in advance if I have missed something.

My old Win7 PC died, so I am in the process of rebuilding a new PC with Windows10.

Its going quite well, but I have run into a problem when installing Hybrid.

The install goes OK, but when I launch it, I get a number of errors relating to VCCEENCC.EXE regarding missing files...

Namely:

AVCODEC-57.DLL
AVUTIL-55.DLL
AVFORMAT-57.DLL
AVFILTER-6

Then at the end I am told "Get Tools Versions got an empty outpuit for VCEEnc The cause might be that the VCEEnc could not be found,... Please redo this with debug output enabled and tell the author."

I have tried re-installing and it didn't help.. Could it be that there is another bundle of tools I need to install? Or is something broken here?

Thanks in advance for your help.
