Installation issue

Hi All,

I have to issues which don't appear to be causing major problems but it'd be good to know whats going on.

Firstly, I couldn't fully uninstall Openworld alpha. A message came up saying "access denied". It uninstalled most things but I had to manually delete a few remaining folders. Any idea why?

After the download and install a whole bunch of EULA and VC_RED files have appeared on my hard drive. Why has this happened and what does it mean?

Thanks
